solved numarical, Mechanical Engineering

Assignment Help:
The following observations were made during a tensile test
on mild steel specimen 60 mm in diameter and X mm long.
Elongation with 50 KN load (within the limit of
proportionality); final diameter = 25. 6 mm, ?L = 0.0304 mm
; yield load = 165 KN; Maximum load = 245 KN, Length of
specimen at rupture = 259 mm. Determine (a) modulus of
elasticity (b) yield point stress (c ) ultimate stress (d) %
Elongation (e) % Reduction
