Solved: A uniform, 8.0-m, 1150-kg beam is hinged to a wall
Chapter 11, Problem 50P(choose chapter or problem)
A uniform, \(8.0-\mathrm{m}, 1500-\mathrm{kg}\) beam is hinged to a wall and supported by a thin cable attached \(2.0 \mathrm{~m}\) from the free end of the beam, (Fig. P11.50). The beam is supported at an angle of \(30.0^{\circ}\) above the horizontal. (a) Draw a freebody diagram of the beam. (b) Find the tension in the cable. (c) How hard does the beam push inward on the wall?

ANSWER:
Solution 50P
Step 1:
Introduction
We need to find the tension, force on the wall due to the beam using the free body diagram.
(a)Free body diagram is as follows:
a=3.46m
W=1150x9.8=11270N
