What is the frictional force in a braking system of a truck if the drum brake pads offer a normal force of 30Newton and the coefficient of friction at the area of contact is 0.5?

What is the frictional force in a braking system of a truck if the drum brake pads offer a normal force of 30Newton and the coefficient of friction at the area of contact is 0.5? Correct Answer 15Newton

Given, Normal force=30Newton Coefficient of friction at the area of contact=0.5 Frictional force = Normal force * Coefficient of friction Frictional force=30*0.5=15Newton.

A haulage rope winds on a drum of radius 500 mm, the free end being attached to a truck. The truck has a mass of 500 kg and is initially at rest. The drum is equivalent to a mass of 1250 kg with radius of gyration 450 mm. The rim speed of the drum is 0.75 m/s before the rope tightens. By considering the change in linear momentum of the truck and in the angular momentum of the drum, find the speed of the truck when the motion becomes steady.

A bus and a truck are available to cross a jungle. The speed of the truck is thrice that of the bus. The capacity of the truck is 50 persons and that of bus is 30 persons. The average occupancy of the bus is twice that of the truck. The tickets for the bus and the truck cost Rs 1 and Rs 1.50 respectively. What is the ratio of the average rupee collection of the truck to that of the bus in a day? Assume there is no wastage time between trips and the occupancy of the bus / truck is defined as the ratio of the actual number of persons boarding it and its capacity.
Which of the following is NOT true about Frictional force? A. Friction is the force which opposes the relative motion of two surfaces in contact. B. The force of friction that acts when a body is moving (sliding) on a surface is called sliding friction. C. Friction in machines wastes energy and also causes wear and tear. D. Rolling friction is much more than sliding friction, the use of ball bearings in a machine considerably reduces friction.
Which of the following statements regarding laws governing the friction between dry surfaces are correct? 1. The friction force is dependent on the velocity of sliding.  2. The friction force is directly proportional to the normal force. 3. The friction force is dependent on the materials of the contact surfaces. 4. The Friction force is independent of the area of contact surfaces.
The accused driver of a truck while driving on the left side i.e., his side of the road, sees a cyclist coming from the opposite direction, but on the wrong side of the road i.e. in the lane on which the truck was being driven; the road being narrow and the truck driver sensing that the cyclist was peddling negligently, maneuvers his truck on the opposite lane and simultaneously the cyclist suddenly moves to his lane and as a result the truck over-runs the cyclist, causing the death of cyclist. The truck driver is not guilty of the offence of causing death by rash and negligent act because:
