Two painters are standing in the positions shown at C
and D on a 300 N scaffolding (beam) which is 4 m
long. One painter weighs W₁ N and the second painter
weighs W₂ N. The scaffolding is supported by two
cables, one at each end as shown in the diagram
below. As they paint, the painters begin wondering
what force (tension) is in each cable. Calculate the
tension in the cable at point A if W₁ = 613 N and W₂ =
500 N
