A truck lifts a heavy weight using a pulley system. At the instant shown the velocity (positive defined to the right) is VTI = 4.5 m/s. After 4 seconds the final velocity VT = 8.5 m/s. Initially, the angle of the cord to the horizontal is B = 30.5 degrees. ma = 95 kg m = 1.5 tonnes. Assume constant acceleration Design a pulley system such that a ratio of 4 to 1 is achieved. Please include a diagram of your system which includes all constant and variable lengths a). b). What is the tension force in the cable after 4 seconds? c). What is the net horizontal thrust force required to product the trucks motion ? d). What is the acceleration of the mass ma after 2 seconds? e). What is the angle B after 4 seconds? 15 m A Pulley System (Ratio 4- 1) Take gravity g = 10 m/s? unless otherwise stated Show all working Note: (1) (2) (3) Weight 45% A truck lifts a heavy weight using a pulley system.
