Question
A Uniform beam 6m long and weighing 60N rests on two supports, P and Q placed 1.0m from each end of the beam. weights of 100N and 80N are hanged from the ends of the beam near P and Q respectively
1. calculate the reactions from P and Q
2. Calculate the reactions at the support.

each support carries half the weight of the beam before the weights are added.
Then the added weight is added to each.
P = 30 + 100
Q = 30 + 80
Then the added weight is added to each.
P = 30 + 100
Q = 30 + 80
