Discussion Forum : UPSC Civil Service Exam Questions - Section 4 (Q.No. 50)
50.
A beam of rectangular section 100 mm x 300 mm carries certain loads such that the Bending Moment at a section A is M ans at another section B it is (M + C).The distance between the sections A and B is 0.5 m and there are no external loads acting between the two sections. If the value of C is 10, 000 Nm, then the maximum shear stress is
1.5 MN/m2
1.0 MN/m2
0.5 MN/m2
0.25 MN/m2

Shear force between A & B is;

Change in BM/Distance = 10000Nm/0.5 = 20000N.
Maximum shear stress =1.5V/bd =1.5 * 20000/0.1 * 0.3.
= 1.0MN/m2.
