Couple M is applied at C on a simply supported beam AB. The maximum shear force on AC will be
A. Zero
B. M
C. 2M/3
D. M/3
Please scroll down to see the correct answer and solution guide.
Right Answer is: D
SOLUTION
Explanation:
ΣFy = 0:
R1 + R2 = 0
ΣMA = 0:
∴ R2 × 3 = -M
\(\begin{array}{l} {R_2} = \frac{{ - M}}{3}\\ {R_1} = \frac{M}{3} \end{array}\)
So maximum shear force = M/3
