Answer:
The answer to the question is
Suki is 1.12 m close to the end of the steel beam before the beam begins to tip
Explanation:
To solve the question we list out the known variables first
Length of steel beam, L = 7.00 m
Weight of steal beam W = 326 N
Distance between supports = 3.00 m
Weight of Suki = 555 N
By moments theory, the sum of moments about a point = 0
and assuming the steal beam is uniform, the weight of the beam will act at the center of the beam
As described the supports are 2.00 m from each end of the beam thus
taking moments about one of the support with Suki between the end of the beam and the support we have
Distance from center of beam to support = 1.5 m
Distance of Suki to the nearest support = x m
therefore 555 × x + 326 × 1.5 = 0
or x = -0.881 m on the other side of the support
Therefore Suki is (2 - 0.881) m or 1.12 m close to the end before the beam begins to tip
