PROBLEM 01
PROBLEM 02
A block having a mass of 5 kg is tied to a cable as
shown. The cable passes through a smooth drum at
D. Another block W is hung as shown with a mass of
4.5 kg. The coefficients of static and kinetic friction
between the block and the plane is 0.2 and 0.1,
respectively. Compute for the following:
The crate shown has a mass of m = 15 kg and is
pulled by the rope as shown. If the coefficients of
static and kinetic friction are ug = 0.30 and ug =
0.20, provide answers for the following. Set 0 =
