Question

What is the tensile stress if a square rod of 10mm side is tested for a tensile load of 1000 kg ?

Answer 1

Answer:

98.1 N/mm²

Step-by-step explanation:

Tensile load,F = Mg

= 1000*9.81

= 9810 N

Here I assumed that the load is applied by a 1000kg mass on earth.

Cross section area of the rod is given by

A = 10*10 mm²

= 100 mm²

Tensile stress on the rod is given by

σ = F/A

= 9810/100 N/mm²

= 98.1 N/mm²
