Problems
Problem 3.1:
A 5kg picture frame is held up by two ropes, each inclined 45o
below vertical, as shown below. What is the tension in each of the ropes?
[Solution]
Problem 3.2:
Consider a 10kg block resting on a frictionless plane inclined
30o connected by a rope through a pulley to a 10kg block
hanging free, as seen in the figure below. What is the direction and
magnitude of the resulting acceleration of the 2-block system?
[Solution]
Problem 3.3:
Two 10kg blocks are connected by a rope and pulley system, as in the
last problem. However, there is now friction between the block and the
incline, given by μs = .5 and μk = .25. Describe the resulting
acceleration.
