Have to give this question ago for Monday, Wondering if I am on the right track.
A rectangular timber tie, 180mm by 80mm, is reinforced by a bar of aluminium of 25mm diameter. calculate the stress in the timber and reinforcement when the tie carries an axial load of 300KN
E of timber=15GN/m^2
E of aluminium=90GN/m^2
Area of timber=180*80=14400-3.14*25^2/4=13909mm^2
Area of aluminium=3.14*25^2/4=491mm^2
Next step is to find strain I think ε of timber=ε of aluminium
ε=δ/E so δ/E of timber=δ/E of aluminium, use this to find stress?
Could anyone teel me if I am on the right track?
