Question

9. A mass of 500kg is supported on column 0.02m x 0.02m. What is the stress in the column. ( g -9.8 m/s2)​

Answer 1

Answer:

Hey there

Force = mass × acceleration

F = 500 × 10

F = 5000 N

Surface area = (side)^2

A = 0.02^2

A = 4 × 10^-4 m^2

Stress = Force / surface area

S = 5000 / 4 × 10^-4

S = 1.25 × 10^7 Pa
