Wrecking ball suspended from a crane: determine tension on the cable and angle
Not what you're looking for?
A 600 kg wrecking ball is suspended from a crane by a cable having negligable mass. If the ball has a speed v= 8m/s at the instant it is at its lowest point, theta= 0 deg., determine the tension in the cable at this instant. Also, determine the angle theta to which the ball swings before stopping. The length of the cable is 12m.

Solution Summary
With calculations and narrative, the tension on the cable and angle is solved.
Solution Preview
Because,
Tension in the cable at angle theta with the vertical:
T = m*g*cos(theta) + m*v^2/l
At the lowest point: theta = 0
m = 600 kg
v = 8 m/s
l = 12 m
g = 9.8 m/s^2
=> T_lowest = m*g + ...
