What is WL Squared over 8?

wL^2/8 is the maximum BM at the centre of a udl of w kg/m for a simply supported beam.

How do you calculate wl2 8?

= wl/2 × L/2 — w× L/2 × L/4 = wl^2 / 8.

How do you calculate bending moment?

Calculate BM: M = Fr (Perpendicular to the force) Bending moment is a torque applied to each side of the beam if it was cut in two – anywhere along its length.

What is the maximum moment?

Explanation: The maximum bending moment occurs in a beam, when the shear force at that section is zero or changes the sign because at point of contra flexure the bending moment is zero. … Such bending moment is called a sagging bending moment or positive bending moment.

How is UDL calculated?

The uniformly distributed load can be substituted by a concentrated load acting in the centre of gravity of the UDL. The total load on beam is the UDL multiplied by the length of the beam, i.e. 5 kN/m × 8.00 m = 40 kN….

Sum of the vertical forces must be zeroΣ Fv = 0
