Discussion
A beam, of 5 m effective span, has its left end 'P' as a free end; whereas its right end 'Q' is a fixed supported end. The beam is subjected to a uniformly distributed load of 3 kN/m on the entire span. Find the point with the maximum shear force.
Answer: A
The beam is a cantilever, free at P and fixed at Q, and loaded with a UDL of 3 kN/m. The shear force at a section a distance x from the free end is \(w x\), which grows steadily towards the fixed end and is greatest at the fixed support:
\[ V_{max} = wL = 3 \times 5 = 15\ \text{kN at Q} \]The shear at the free end P is zero, and at the midpoint it is 7.5 kN and at 1 m from the fixed support it is 12 kN, both smaller than the 15 kN at Q.
