Chapter 13, Problem 23P

A small inspection car that is being used to inspect ski lifts cables has a mass of 150 kg. It runs on ski lift cable, which makes an angle of 35oto the horizontal. The car is controlled by the attached horizontal cable under a tension of P = 2 kN. Determine the acceleration of the car and the total force exerted by  the supporting cable on the wheels.

The 18-Mg truck hauls the 38-Mg trailer. If the unit starts from rest on a level road with a tractive force of 17 kN between the driving wheels of the truck and the road, compute the tension Tin the horizontal drawbar and the acceleration a of the rig. 38 Mg 18 Mg Answers: T = kN m/s? =

A cart has a mass of 1.5 kg. It is given some initial push toward a sensor and is slowed by a hanging mass which makes the cart turn around and speed up as it returns to its original position. This situation is illustrated in the attached image. If the acceleration towards the sensor is 0.5 m/s2 and the accaleration away from the sensor is 0.15 m/s2,  a. draw the free body diagrams for the cart moving towards the sensor and away from the sensor. b. Write Newton's law for both situations and solve for the frictional force and for the force from the hanging mass.

The 3.5-Mg engine is suspended from a spreader beam AB having a negligible mass and is hoisted by a crane which gives it an acceleration of 4 m/s? when it has a velocity of 2 m/s. Determine the force (kN) in chains CA and CB during the lift. Draw the FBD for the entire system and the FBD for the chains connected to A, B, and C. Show all necessary math and include all units. 60°

Determine the accelerations of bodies A and B and the tension in the cable due to the application of 60-lb force. Neglect all friction and the masses of the pulleys. 150 lb 75 lb P= 60 lb A B

Problem 6: The rear wheels of the truck shown provide traction force of 2000 N. If the truck has a mass of 1900 kg, determine the its acceleration and the normal force exerted on each pair of front and rear driving wheels. Also, find the time needed for the truck to achieve a speed of 20 m/s starting from rest. The front wheels are free to roll. Neglect the mass of the wheels. 2 m +1.5 m-

Q2: The safe S has weight Ws and is supported by the rope and pulley arrangement shown. If the end of the rope is given to a boy B of weight Wb, determine his acceleration if in the confusion he doesn't let go of the rope. Neglect the mass of the pulleys and rope. Given: Ws = 200 lb, Wb = 90 lb

2. A mass of 0.10 slug in space is subjected to an external vertical force of 3 lb. If the local g=32.2ft/s? and if friction effects are neglected determine the acceleration of the mass if the external vertical force is acting a. Upward b. downward

Please provide fbd with tension (and direction of tension) and kinetic diagram with assumed direction of weight
