A Light Board That Is 10 M Long Is Supported

Short Answer

A light board that is 10 m long is supported by two sawhorses, one at one end of the board
and a second at the midpoint. A 40-N object is placed between the two sawhorses, 3.0 m
from the end and 2.0 m from the center. A second object, with a weight of 15 N, is placed
on the supported end. What magnitude forces do the sawhorses exert on the board?
