I have a question I have been given to work out shear force for.
The question is an elastomeric bearing pad is subjected to a shear force V
the top plate is found to have displaced by d = 12mm
dimensions of the top pad are a = 150mm by b = 200mm, the thickness (d) is 120mm. the modulus of rigidity G is 2 MPA
I have found a formula which is shear stress is t=Gy
y = d/h so 12 / 120 = 0.1
shear stress 2000 x 0.1 = 200 Kn
i fear i have done something wrong because i haven't used the dimensions of the plate. I have a formula which gives the average stress which is stress = v / ab but if i rearrange i get v = ab / stress
