The weight of the bar is 2 kg. Find the pressure it exerts on the table if it is 100 mm long and 200 mm wide.

To solve this problem, we will use the formula for finding the pressure.
p = F / S.
p – body pressure.
F is the force of gravity.
S is the surface area.
The formula for finding the force of gravity.
F = m * g.
The formula for finding the area.
S = a * b.
We get:
p = (m * g) / (a * b).
100 mm = 0.1 meter.
200 mm = 0.2 meters.
p = 20 / 0.02 = 1000 N / m ^ 2 = 1000 Pa.
Answer: 1000 Pa.
