Question:

Chapter 2, Problem 2/174 Determine the velocity of cart A if cylinder B has a downward velocity of 2.6 ft/sec at the instant

Chapter 2, Problem 2/174 Determine the velocity of cart A if cylinder B has a downward velocity of 2.6 ft/sec at the instant illustrated. The two pulleys at C are pivoted independently. The velocity of A is positive if down the slope, negative if up the slope. UB B Answer: VA = ft/sec the tolerance is +/-2%

Answers

3Va + 2Vb = 0

so , Va = -(2/3) * Vb

Va = -(2/3) * 2.6

Va = -1.733 ft/sec

so velocity of block A is Va = -1.733 ft/sec it is negative because it's up the slope.
