Question 3 (a) Consider a vehicle resting on a slope with an inclination angle $\theta$ to the horizontal. The vehicle has total mass of 6000 kg and is held at rest on a slope of $12^\circ$. It has a wheel base of 230 cm and its center of gravity is 120 cm from the rear axle and 155 cm above the ground level. (i) Derive the equations for the normal reactions at the wheels and find their respective values. (ii) Assuming that sliding does not occur first, what will be the angle of slope so that the vehicle will overturn? (iii) Assuming all the wheels are to be braked, what will be the angle of the slope so that the vehicle will begin to slide if the co-efficient of adhesion between the tyre and the ground is 0.45? (15marks) (b) For a motor vehicle, the rolling resistance is given by $13.6 + 0.6965 V$ and the air resistance by the expression $0.0827 V^2$ the resistance being in N and V the speed in km/hr. If the transmission efficiency is 88%, calaculate the bkW required for a top speed of 128 km/h. Assuming that the engine torque at 48km/h in top gear is 25% more than that at 128 km/h and the vehicle inertia corresponds to a weight of 17805N, calaculate the acceleration in m/s$^2$ at 48 km/h.

(Consider two values to be equal if they are within 3% of each other.) The total power is equal to the sum of the powers dissipated by the resistors. The total power is less than the sum of the powers dissipated by the resistors. The total power is greater than the sum of the powers dissipated by the resistors.
