Questions
For the pulley system shown in Fig. , each of the cables at A and B is given a velocity of 2 m in the direction of the arrow. Determine the upward velocity v of the load m.
detailed solution
Correct option is A
vA = 2ms-1 (towards right)VP1=VA2=1 ms−1(upwards)VB= 2 ms−1(towards left)2VP2=VB+VP1VP2=VB+VP12=2+12=1.5 ms−1Talk to our academic expert!
