Answer to Question #123764 in Mechanical Engineering for Samuel

Question #123764
An aluminium bar 600mm long, with diameter 40mm, has a hole drilled in the center of the bar. The hole is 30mm in diameter and is 100mm long. If the modulus of elasticity for the aluminium is 85GN/m2, calculate the total contraction on the bar due to a compressive load of 180kN.

Given:

For aluminum bar

compressive Load (P)=180KN

modulus of elasticity (EAL)=85GN/m2

Total Length(L) = 600 mm

Diameter aluminium bar (do) = 40 mm

Hole diameter (di)= 30 mm

Rest bar lenght (L1)=(600-100)=500 mm

Hole length (L2)= 100 mm

Find the total contraction on the bar due to a compressive load .
