7.4 - more on moments

Question 1

the equation used to calc the support force of a pole (with weights) balanced on 1 beam

Answer 1

S = w₀ + w₁ + w₂ …

(W0 = ples weight)

Question 2

steps to calc the support forces of a pole (with weights) balanced on 2 beams

with calculations

Answer 2

1) Add up the total weights (W0 + W1 + W2…)
2) Understand S1 + S2 = sum of total weights
3) have one (S1)of the support beams act as a pivot, calc the distances of the weights and other beam

S₂ = (W₀d₁ + W₁d₁…)/ D

(D = distance between the beams)

4) S₁ = sum of weights - S₂

Question 3

what is a couple

Answer 3

a pair of parallel, equal size and opposi__te forces that create a moment about a point

Question 4

What can the moment of a couple be referred as

Answer 4

Torque
