XA Problem statement: The mass-pulley Data & Diagram: (Draw and label completely)
system is designed to consist of log A, block
B, and collar D as shown. Given that both
log A and collar D move with a constant
acceleration of 0.2g downward (g=9.81 m/s)
and that the system starts from rest,
determine
Find;
B
XD
(a) the acceleration of block B at this
instant,
(b) the corresponding acceleration of collar
D
D relative to block B, and
A
[+2]
(c) the velocity of log A after it has
displaced 10 cm, the corresponding
time, and displacement of block B.
Assumption(s);
Theory:
1. Cable or rope remains taut. [+ 1]
Kinematics relation; [1]
2. All frictional effects are negligible.
Length of cable = constant
