What is work?
Work is defined as the product of applied force and the distance through which the body is displaced on which the force is applied.
Work may be zero, positive and negative.it depend on the diection of body displaced . if the body is displaced in thw same direction of force it will be positive .
while if the displacement is in the opposite direction of force applied the work will be negative work . if their is no displacement of the body the work done will b e zero.
As given in question wall is stationary diplacement will be zero so in that work will also z
The given data in the problem is;
x is the displacement in the horizontal direection=22m
y is the displacement in the verical direection=9.6m
W is the weight of lumber = 45 N
[tex]\rm W=F\times y[/tex]
[tex]\rm W=F\times y \\\\\rm W=45\times 9.6\\\\ \rm W=432\;Nm[/tex]
Hence Work was done by the workman will be 432 Nm.
