Sagot :
The upward force on each supporting plank is 200 N
The given parameters include;
- weight of the plank, W₁ = 400 N
- length of the plank, l = 2 m
- upward force of each supporting plank, = W₂ and W₃
To show that the upward force of each supporting plank is 200 N, make the following sketch.
W₂ W₃
↑ ↑
-----------------------------------------------------------------------
0.2m ↓ 0.2m
400 N
- The two supporting planks keeps the 2m plank in equilibrium position.
- If the plank is in equilibrium position the sum of the upward forces equals sum of the downward force.
W₂ + W₃ = 400 N
But the distance of each supporting plank from the end is equal, (0.2m).
Then, W₂ = W₃
2W₂ = 400 N
W₂ = 400N/2
W₂ = 200 N
W₃ = 200 N
Therefore, the upward force on each supporting plank that keeps the plank in equilibrium position is 200 N.
