Question

The rigid bar BDE is supported by two links AB and
CD. Link AB is made of aluminum (E = 70 GPa) and
has a cross-sectional area of 500 mm?; link CD is
made of steel (E = 200 GPa) and has a cross-sectional
area of 600 mm². For the 30-KN force shown,
determine the deflection (a) of B, (b) of D, (C) of E.

Answer 1

Answer:

I don't understand question

Answer 2

Answer:
For Delta Ab= 0.514mm
For Delta DC=0.300mm
For Delta E = 1.928mm

Explanation:

Just find the internal force for every link AB and DC using statics
Then for E use integral to find the answer
