*4–156. Determine the length b of the triangular load and
its position a on the beam such that the equivalent resultant
force is zero and the resultant couple moment is 8 kN # m
clockwise.
Please briefly explain why you feel this question should be reported.
4–155. Replace the distributed loading by an equivalent
resultant force and specify where its line of action intersects
a vertical line along member BC, measured from C.
Please briefly explain why you feel this question should be reported.
4–154. Replace the distributed loading by an equivalent
resultant force and specify where its line of action intersects
a horizontal line along member AB, measured from A.
