1.	A steel rod is rigidly clamped at its two ends. The rod is under zero tension at 20∘ C. If the temperature rises to 100∘ C, what force will the rod exert on one of the clamps? Area of cross section of the rod = 2.0 mm2. Coefficient of linear expansion of steel =12.0×10−6 ∘ C−1 and Young's modulus of steel = 2.00×1011 Nm−2.
Answer» A steel rod is rigidly clamped at its two ends. The rod is under zero tension at $20^{\circ} C$ . If the temperature rises to $100^{\circ} C$ , what force will the rod exert on one of the clamps? Area of cross section of the rod = $2.0 m m^{2}$ . Coefficient of linear expansion of steel $= 12.0 \times 10^{- 6}^{\circ} C^{- 1}$ and Young's modulus of steel = $2.00 \times 10^{11} N m^{- 2}$ .

A parallel-plate capacitor having plate area A and plate separation d is joined to a battery of emf E and internal resistance R at t=0. Consider a plane surface of area A/2, parallel to the plates and situated symmetrically between them.

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
