It is easier to draw up a wooden block along an inclined plane than haul it up vertically because

Answer»

the friction is reduced
the mass becomes smaller
G becomes smaller
only a PART of the weight has to be overcome

Solution :For a body placed on an inclined plane, the acceleration down the plane `=g SIN theta`.
`therefore ` The force to be applied to draw it UPWARDS `= MG sin theta`
While for lifting it upwards, the force to be applied is mg.
`therefore mg gt mg sin theta`
Thus on the inclined plane, only a part of the weight has to be overcome.
