A person with weight 700 N stands d = 2.00 m away from the wall on a l = 5.00 m

Question

A person with weight 700 N stands d = 2.00 m away from the wall on a l = 5.00 m beam, as shown in this figure. The weight of the beam is 2,000 N. Define upward as the positive y direction and to the right as the positive x direction. (a) Find the tension ?n the wire. (Enter the magnitude only.) (b) Find the horizontal component of the hinge force. (Indicate the direction with the sign of your answer.) N (c) Find the vertical component. (Indicate the direction with the sign of your answer.) N Use the conditions the net force and net torque must satisfy in equilibrium to find force components exerted by the hinge. N

Explanation / Answer

part C:

vertical Components add upto sero

Rv - 700 - 2000 + T sin 30 = 0

Rv = 2700 - (2560* 0.5)

Rv = 1420 N

this acts along +y direction
