The baggage truck A has a mass of 800 kg and is used to pull each of the 300kg cars. If the tractive force F on the truck is 480N, determine the acceleration of the truck. What is the acceleration of the truck if the coupling at C suddenly fails? The car wheels are free to roll. Neglect the mass of the wheels.

handwritten solutions pls, thank you!@

A,B,&C please and thank

by the rope and pulley arrangement shown. If the end of 13-37. The safe S has a weight of 200 lb and is supported the rope is given to a boy B of weight 90 lb, determine his acceleration if in the confusion he doesn't let go of the rope. Neglect the mass of the pulleys and rope. [thw & baol pl fl S B doo2 e 1000 015671 ONT LIE-EI

A7.0-Mg truck is resting on the deck of a barge which displaces 329 Mg and is at rest in still water. If the truck starts and drives toward the bow at a speed relative to the barge vrel = 7.1 km/h, calculate the speed v of the barge. The resistance to the motion of the barge through the water is negligible at low speeds. P'rel = 7.1 km/h 7.0 Mg 329 Mg- Answer: v = i km/h

3: An equipment works on a road with a sandy clay soil with coefficient of traction (0.42). - Find the maximum force can be provided by this equipment before sliding the driving tires. If the total weight on the driving wheels is (25 ton)? - What is the maximum coefficient of traction that the equipment can work with it if the maximum force of its engine is 12000 Kg, for the same weight?

3. The tow truck’s front wheel will be lifted off the ground if the moment of the load W about the rear axle exceeds the moment of the 6200-lb weight of the truck. Determine the largest Wthat may be safely carried by the tow truck.

A locomotive on BG track with four pairs of driving wheels each carrying axle load of 20 tonnes is required to haul a train at a speed of 80 kmph. The train is made to run on a level track with curvature of 2°. Calculate the maximum permissible load that can be pulled by the engine. Take hauling capacity as one-sixth of the load on driving wheels.
