Question

aGiven that a beam with the geometry and loading indicated (C = 3200 N andD = 1500 N). Determine the moment of the loads on this beam using thereaction at B as the center of moments.

Answer 1

Given,

The load at point C, C=3200 N

The load at point D, D=1500 N

The distance between point B and D, d₁=2 ft

The distance between point B and C, d₂=6 ft

The distance between point A and point B, d₃=10 ft

The moment of the load at point C with B as the center of moments is given by,

`M_C=C* d_2`

On substituting the known values,

`\begin{gathered} M_C=3200*6 \\ =19200\text{ N ft} \end{gathered}`

The moment of the load at point C is 19200 N·ft

The moment of the load at point C with B as the center of moments is
