2.7 m from the left end of the plank. The plank
is supported by two supports at distances X1 = 0.8 m
and X2 = 3.7 m from the left end of the plank.
The picture shown below includes the forces acting
on the plank to make it easier for you. Wp and WB are
the weights of the plank and box respectively. F1 and
F2 are the support forces.
Using the fact that the plank is in static equilibrium,
calculate the support force F2, Specify your answer in
Sl units up to one decimal place. Do not include units.
