question 28
compute the maximum shear (v) for the cantilever beam shown below. assume l = 12 ft and w = 720 lb
v = 720 lb
none of these answers are correct
v = 30 lb
v = 360 lb
v = 60 lb

Explanation:

Step1: Analyze shear - force in cantilever beam

For a cantilever beam with a uniformly - distributed load \(W\) over its entire length \(L\), the maximum shear force occurs at the fixed end. The maximum shear force \(V\) is equal to the total load acting on the beam.

Step2: Identify the total load

Here, the total load \(W = 720\) lb. So the maximum shear force \(V\) is equal to the total load acting on the beam.

Answer:

A. \(V = 720\) lb
