Assume if the shear stress in steel exceeds about 4.00 108 N/m2 the steel ruptures.
(a) Determine the shearing force necessary to shear a steel bolt 1.25 cm in diameter.
(b) Determine the shearing force necessary to punch a 2.60-cm-diameter hole in a steel plate 0.590 cm thick.
here,
for steel to repture,
the shearing stress , S = 4 * 10^8 N/m^2
a)
diameter , d = 1.25 cm = 0.0125 m
the shearing force necessary to shear a steel bolt , F = S * pi * ( d/2)^2
F= 4 * 10^8 * pi * ( 0.0125/2)^2 N
F = 4.91 * 10^4 N
b)
diameter , d = 2.6 cm = 0.026 m
the shearing force necessary to shear a steel bolt , F = S * pi * ( 0.026/2)^2
F= 4 * 10^8 * pi * ( 0.026/2)^2 N
F = 2.12 * 10^5 N

A square steel plate is 8.00 cm on a side and 0.300 cm thick. Assume that the plate is oriented with the square faces horizontal to the ground. a force of magnitude 7.00×105 N is applied to both the top and bottom surfaces of the plate (the square sides). Each of the forces is applied in a direction parallel to the surface they are exerted on, and they point in opposite directions. Find the shear strain caused by these forces....
