Question

a bar one meter long with square cross section (side of square being 5mm) is supported horizontally at its ends and is loaded at the middle point. It is depressed by 1.96mm by a load of 100 gm. calculate the young's modulus of the material of the bar

Answer 1

Answer 2

Explanation:

if the point of elasticity is not reached then the young modulus will stay constant . if the doubling of the load exceeds the point of elasticity, the young modulus will increase or decrease depending on the type of material. no it will not except tension will grow
