Q1. A motorcycle has a constant speed of 23.10m/s as it passes over the top of a hill whose radius of curvature is 120m. The mass of the motorcycle and driver is 376 kg. Find out the magnitude of the normal force that acts on the cycle.

Q2. The lintel of pre stressed reinforced concrete is 1.50m long. The concrete encloses one steel reinforcing rod with cross-sectional area 1.00cm2. The rod joins two strong end plates. The cross-sectional area of the concrete perpendicular to the rod is 47.5 cm2. Young's modulus for the concrete is 3.00 x 10^10 N/m2. After the concrete cures and the original tension T1 in the rod is released, concrete is to be under compressive stress 8.65 x 10^6 N/m2.
