Question

(a) A cantilever of 6m length carries an U.D.L of 12 kN/m over the full span. If the free end is supported by a prop, find the reaction at the prop and also draw the S.F. and B.M. diagrams. (b) What is the difference between weir and barrage?

Answer 1

To find the reaction at the prop of a cantilever, use the equation for the sum of the moments at the free end. Plot the moments to obtain the B.M. diagram and plot the forces to obtain the S.F. diagram.

Step-by-step explanation:

The reaction at the prop of a cantilever can be found by using the equation for the sum of the moments at the free end of the cantilever. In this case, the sum of the moments would be equal to zero. The reaction at the prop would be equal to the total moment caused by the uniform distributed load (UDL) divided by the length of the cantilever. The B.M. (Bending Moment) diagram can be obtained by plotting the moments at different points along the length of the cantilever, while the S.F. (Shear Force) diagram can be obtained by plotting the forces at different points along the length of the cantilever.
