Question

A force P of 70 N is applied by a rider to the
front hand brake of a bicycle (P is the resultant of an
evenly distributed pressure). As the hand brake pivots at
A, a tension T develops in the 460-mm long brake cable
(Ae = 1.075 mm2 ), which elongates by δ = 0.214 mm.
Find the normal stress d and strain  in the brake cable.

Brake cable, L= 460 mm Hand brake pivot A
37.5 mm
P (Resultant
of distributed
pressure)
50 mm
- Uniform hand
brake pressure
100 mm
