Question
The figure shows a 32.8 kg, uniform ladder of length L, hinged to a horizontal platform at point P1 and anchored with a steel cable of the same length as the ladder attached at the ladder's midpoint. The ladder makes an angle of 50degrees with the horizontal.
A. Calculate the magnitude of the tension in the cable when a 75.5kg person is standing three-quarters of the way up the ladder.
Answer given is 2000N.
B. Calculate the components of the force in the hinge when an 75.5kg person is standing three-quarters of the way up the ladder. (include directions).
Answer given is Fx(1840N), Fy(1840N)
Explanation / Answer
here i assumed that angle between the rope and the floor is 30.0
