Problem 50P

A uniform, 8.0-m, 1150-kg beam is hinged to a wall and supported by a thin cable attached 2.0 m from the free end of the beam (?Fig. P11.46?). The beam is supported at an angle of 30.0° above the horizontal. (a) Draw a free-body diagram of the beam. (b) Find the tension in the cable. (c) How hard does the beam push inward on the wall?

Step-by-Step Solution:

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 Step 2 of 3: (b)Tension at the cable Finding the net torque at the point of contact with wall: T=10112.69N
