type kerbs : When the pedestrian traffic is high, these kerbs are provided. Their height is 15 cm above the pavement edge. This type of KERB prevents ENCROACHMENT of parking vehicles, but at acute emergency it is possible to drive over this kerb with some difficulty.Barrier type kerbs : They are designed to discourage vehicles from leaving the pavement. They are provided when there is CONSIDERABLE amount of pedestrian traffic. They are PLACED at a height of 20 cm above the pavement edge with a steep batter.Submerged kerbs : They are used in rural roads. The kerbs are provided at pavement edges between the pavement edge and shoulders. They provide lateral confinement and stability to the pavement.

The evaluation of bituminous concrete mixes for their tendency to RUTTING has been an important research field for MANY years. Rutting is a MAJOR type of distress encountered in bituminous pavements. The Finite Element Method (FEM) is a numerical analysis technique to obtain various structural parameters such as stress, strain and deflection of pavement layers. The objective of this paper is to study the sensitivity of these variables in reducing the vertical surface deflections, the critical tensile strains at the bottom of the bitumen layer and the critical compressive strains on the top of subgrade using the finite element method. This study has been carried out in order to compare the performance of flexible pavement using the finite element method and KENLAYER. Vertical surface deflections in flexible pavements have always been a major concern and are used as a criterion for pavement design. It is desirable to reduce the deflections as much as possible. This paper DEALS with ways to reduce deflections by varying the design configuration, such as increasing the Hot Mix Asphalt (HMA) modulus, the base modulus, sub base modulus and the subgrade modulus. Another objective of the present study is to investigate the effectiveness of TWO different methods in reducing vertical surface deflections (w

The gravitational CONSTANT is equal to the circumference of the Planck energy DIVIDED by the mass it has created, multiplied by C2. ... The gravitational constant is considered by scientists to be universaland INVARIABLE. It is considered the same value no matter where in the universe mass is found.

Heya mate here is your ANSWER
following are the factors AFFECTING friction
Surface on which the OBJECT is moved or the nature of the surface. i.e., rough surface, smooth surface, liquids etc.

The weight of the object or the amount of force on the surface by the object.

Or is it weightless?

The sky does have weight. It is made of air and air is made of all kinds of gas molecules. Those gas molecules have weight!

If sky has weight, then how is earth carrying that weight?

Weight of the air is evenly distributed over the earth’s surface. Since air moves AROUND EASILY, it presses on us from all the directions. If it was to be only on top of our heads, it would knock us down to the ground.

How much does air weigh?

The average weight of air that presses down on us (called air pressure) is 14.7 lbs (6.6 Kg) per square inch of earth’s surface. Which is roughly more than 11 billion billion pounds (5.2 million billion metric tonnes)

This means the sky weighs 14.7 lbs per square inch of earth surface which is roughly 11 billion billion pounds.

So, you can say that sky weighs one millionth of the mass of the Earth.

Which equals to 570,000,000,000,000 ADULT INDIAN elephants!

On street PARKING means the vehicles are parked on the SIDES of the street itself. This will be usually controlled by GOVERNMENT agencies itself. Common TYPES of on-street parking are as listed below. This classification is based on the ANGLE in which the vehicles are parked with respect to the road alignment.

Traffic signs are a METHOD of warning and guiding drivers, helping to regulate the FLOW of traffic among vehicles, pedestrians, MOTORCYCLES, bicycles and others who travel the STREETS, HIGHWAYS and other roadways.

The geometric design of highways deals with the dimensions and layout of visible features of the highway. The emphasis of the geometric design is to address the requirement of the driver and the VEHICLE such as safety, comfort, efficiency, etc. The features normally considered are the cross section elements, SIGHT DISTANCE consideration, horizontal curvature, gradients, and intersection. The design of these features is to a great extend influenced by driver behavior and psychology, vehicle characteristics, traffic characteristics such as speed and volume. Proper geometric design will help in the reduction of accidents and their SEVERITY. Therefore, the objective of geometric design is to provide optimum efficiency in traffic operation and maximum safety at reasonable cost. The planning cannot be done stage wise in this case like that of a pavement, but has to be done well in advance. The main components that will be discussed are:

Factors affecting the geometric design,

Highway alignment, road classification,

Pavement surface characteristics,

Cross-section elements including cross slope, VARIOUS widths of roads and features in the road margins.

Sight distance elements including cross slope, various widths and features in the road margins.

Horizontal alignment which includes features like super elevation, transition curve, extra widening and set back distance.

Vertical alignment and its components like gradient, sight distance and design of length of curves.

Intersection features like layout, capacity, etc.

Pavement Evaluation. Pavement PERFORMANCE is a function of its relative ABILITY to serve traffic over a period of time (Highway Research Board, 1962). Originally, a pavement'srelative ability to serve traffic was determined QUITE subjectively by VISUAL inspection and experience.

===========

the RELATION between pressure and area is that
area is inversely PROPORTIONAL to pressure.

which IMPLIES more is the pressure LESS is the area and vice versa.

The heating effect of current is calculated by:

H = I ^ 2 * R * t

I = current

R  = resistance

t = time

The advantages are as FOLLOWS:-

⇒ The electric toasters need current to PRODUCE heat .

⇒ The electric IRON works on this principle too.

⇒ In cookers the same principle is used .

Hope it helps you

We have to find stopping distance, S
initial speed , u = 75 km/h = 75 × 5/18 = 125/6
= 20.83 m/s
total reaction time , t = 2.8 second.
before applying BREAK BODY in motion with constant speed.
so, distance TRAVELLED in reaction time, S' = ut
= 20.83 × 2.8 m = 58.32 m

now, after applying break, body start to decrease its speed with an acceleration.
because surface is ROUGH and coefficient of roughness is given 0.33
so, friction force = ma
umg = ma => a = ug = 0.33 × 10 = 3.3 m/s²

now, distance travelled by body after applying break , S" = u²/2ug = (20.83)²/2 × 3.3
= 65.74 m

so, stopping distance , S = S' + S"
= 58.32 + 65.74
= 124.06 m

Total MASS of the system (cyclist and bike), M=mc+mb=90 kg

Initial velocity of the system, u=6.0 km/h=1.666 m/sec

Final velocity of the system, ν=12 km/h=3.333 m/sec

From work-energy THEOREM, we have:
INCREASE in K.E.=12Mν2−12mu2=1290×(3.333)2−12×90×(1.66)2=499.4−124.6=374.8=375 J
