A steel flat of thickness 10mm tapers uniformly from 60mm at one end to 40mm to the other end in a length of 600mm. If the bar is subjected to a load of 60 kN, find its extension. Take E = 200 GPa. What is the percentage error if average area is used for calculating the extension?
Percentage error = 1.345
Can you share how you got this answer?
How is the formula arrived? Is there any derivation? For calculation of extension!!!
yes, this formula is of change in length of trapezoidal section
Thanks…can u share the derivation?
Good work @ashokraja94 this is right!
Nice work guys!
