QUESTION 2
Figure Q2 shows a plate that is supported by two brackets on each side. The plate is subjected to
axial load F. A 10 mm diameter bolt is used to hold the plate. Then, the bracket is mounted to
wooden block using two similar bolts. It is given the yield stress, ay and shear yield stress, Ty of
the bolt is 140 MPa and 90 MPa respectively:
a)
b)
c)
State which bolt/s is/are subjected to tensile load and determine the
tensile stress of the bolt/s.
State which bolt/s is/are subjected to transverse shear load and
determine the shear stress of the bolt/s.
Based on the safety factor of 2, determine whether the bolts A, B and
Care safe or unsafe.
