5 0

Explanation:

Sum the moments about the hinge H.  Assume anticlockwise is positive and clockwise is negative.

∑τ = Iα

(20 N) (500 mm) − F (120 mm) = 0

F = 83 N

Pressure = force / area

P = 83 N / 0.0036 m²

P = 23,000 Pa

How to find the energy of an 8 pound weight with e=mc2
Nastasia [14]
Change the 8 pounds to kilograms (divide it by 2.2). Then multiply the kg by the speed of light (300,000,000 m/sec) squared. You get a very big number. It's the number of joules of energy equivalent to 8 lbs of mass.
