A $3.75 \mathrm{~m}$ Long Horizontal Beam of Negligible Weight Is Supported at Each

Short Answer

A $3.75 \mathrm{~m}$ long horizontal beam of negligible weight is supported at each end by a column. When a vertical load is applied, the reaction at the left column is $124 \mathrm{~N}$ and the reaction at the right column is $617 \mathrm{~N}$ .
(a) What was the size of the vertical load?
(b) How far from the left end was the load applied?
