Consider a simply supported beam PQ as shown in the figure. A truck having 100 kN on the front axle and 200 kN on the rear axle, moves from left to right. The spacing between the axles is 3 m. The maximum bending moment at point R is _________ kNm. (in integer)

A simply supported beam is subjected to a uniformly distributed load. Which one of the following statements is true?

The following statements are related to bending of beams:

$${\rm I}.$$ The slope of the bending moment diagram is equal to the shear force.
$${\rm II}.$$ The slope of the shear force diagram is equal to the load intensity.
$${\rm III}.$$ The slope of the curvature is equal to the flexural rotation.
$${\rm IV}.$$ The second derivative of the deflection is equal to the curvature.

The only FALSE statements is

A curved number with a straight vertical leg is carrying a vertical load at $$Z,$$ as shown in the figure. The stress resultants in the $$XY$$ segment are. Bending movement, shear force and axial force
