Question
a) the horizontal component of the force extremes by the hinge on the beam b) what is the magnitude of the force that the beam exerts on the hingeI solved the Answer to part a which is 34.3 N but I'm having trouble with b. A 28.9 kg beam is attached to a wall with a hinge and it's far end is supported by a cable. The angle between the beam and the cable is 90degrees. If the bean is inclined at an angle of theta=14degrees with respect to the horizontal what is a) the horizontal component of the force extremes by the hinge on the beam b) what is the magnitude of the force that the beam exerts on the hinge I solved the Answer to part a which is 34.3 N but I'm having trouble with b.
Explanation / Answer
alon horizantal
Fx = T*cos(90-14) = 34.3 N
T = 141.7 N
along vertical Fnet = 0
T*sin76 + Fy = m*g
Fy = 153.4 N
F = sqrt(Fx^2 + Fy^2)
F = 157.2 N
