A Horizontal Beam of Negligible Weight Is $12.0 \mathrm{~m}$ Long and Is Supported by Columns at Each End

Short Answer

A horizontal beam of negligible weight is $12.0 \mathrm{~m}$ long and is supported by columns at each end. A vertical load of $6500 \mathrm{~kg}$ is applied to the beam $x$ metres from the left end. Find $x$ so that the reaction at the left column is $3800 \mathrm{~kg}$ .
