Question

E) What is the direction of the force that the hinge at point A exerts on the left-hand beam?

Part D Two identical, uniform beams weighing 260 N each are connected at one end by a frictionless hinge. A light horizontal crossbar attached at the midpoints of the beams maintains an angle of 53.0between the beams The beams are suspended from the ceiling by vertical wires such that they form a "V", as shown in the figure (Figure 1) What is the direction of the force that the hinge at point A exerts on the right-hand beam? i A2op with the direction to the right Figure 1 of 1 Submit My Answers Give Up Part E What is the direction of the force that the hinge at point A exerts on the left-hand beam? i A2 Symbols with the direction to the right Submit My Answers Give Up Provide Feedback Continue

Explanation / Answer

( D)

Due to symmetrical arrangement, the upward pull of the wire on each beam is balanced by the downward pull of gravity. Hence, the hinge does not exert vertical force. It must balance the outward push of the cross bar.

The hinge exerts a force Fc ( force exerted by cross bar on beam ) horizontally to the left for the right-hand beam.

The hinge exerts a force Fc ( force exerted by cross bar on beam ) horizontally  to the right for the left-hand beam.
