The jaws of the bolt cutter shown are connected by two links AB. The cross-sectional area of each link is 750 mm2.
(a) What average normal stress is induced in each link by the 90 N forces exerted on the handles?
(b) The pins connecting the links AB to the jaws of the bolt cutter are 20 mm in diameter. What average shear stress is induced in the pins by the 90 N forces exerted on the handles?
