The 5W motor operated for 10s and pulled the cable by 2m. The cable is connected to a single fixed followed by a single movable pulley. Another cable connects the movable pulley and an initially stationary Block A (4kg) on a horizontal Surface X. Between Block A and the horizontal Surface X, Mstart=0.15 and μslide = 0.1. Just after 0.1s, Block A had an elastic collision with Block B (2kg) on a horizontal Surface Y with negligible friction. 1) Calculate the force experienced by the cable, that is connected to Block A. 2) Calculate the net force on Block A, before the collision. 3) Calculate the velocity of Block A, just before collision. 4) Calculate the velocity of Block B, after collision. 5) Suggest how to increase the velocity of Block B by 50%.

A hungry rabbit weighing 10 N moves out on a beam in an attempt to get some of the carrots hanging in a bag at the end of the beam. The beam is uniform, weighs 30 N and is 10 m long. The bag of carrots weigh 10 N. The beam is hinged horizontally to a wall and the end of the beam is connected to the wall by a cable which has an angle of 30° with the horizontal. If the cable can only withstand a maximum tension of 65 N, what is the maximum distance from the wall the rabbit can move before the cable breaks ? Wall 30 Carrots

A belt drive is used to transmit power from an electric motor to a compressor for a refrigerated truck. The compressor must still operate when the truck is parked and the engine is not running. The 50-hp electric motor is rated at 150+X rpm (where value of X = 50), and the motor sheave diameter is 5+d1 in. (where value of d1 = 5). The compressor sheave has 8+d2 in (where value of d2 = 5) diameter. The center distance of the drive is 15 in. Determine the appropriate industrial V belt size, the length of belt, operating speed of compressor and belt speed.

TT α = 15° Pin- Cable- Figure 1 A lifeboat hangs from a ship's two davits, as shown in Figure 1. A pin of diameter d=20 mm passes through each davit and supports two pulleys, one on each side of the davit. Cables attached to the lifeboat pass over the pulleys and wind around winches that raise and lower the lifeboat. The lower parts of the cables are vertical and the upper parts make an angle a=15° to the horizontal. The allowable tensile force in each cable is 8 kN, and the allowable shear stress in the pins is 27.5 MPa. The weight P that will be carried in the lifeboat and the weight of the boat, W-6.7 kN, have a common line of action which passes through the middle of the two small pulleys attached to the boat. a. Draw the free body diagram (FBD) of the lifeboat and express the tensile force of the cables I as a function of the useful load P. b.

Problem 1: Three vertical posts AD, BE, and CF are held between two horizontal rigid plates. Posts AD and CF are made of steel (Es = 200 GPa) and have cross sectional areas of 1000 mm² each. Post BE is made of aluminum (Ea = 73.1 GPa) and has a cross sectional area of 1500 mm². Initially, there is a small gap of 0.1 mm between BE and the top horizontal plate. Then a vertical force of P = 410 kN is applied, which is more than sufficient to close the gap completely. D -0.5 m B E -0.5 m- 0.4 m F Determine the normal stresses in posts AD, BE, and CF (both magnitude and sign).
