Example Problem $5-1.$ Home work $1$

For the flat steel spring shown in Figure $5-6,$ compute the maximum stress, the minimum stress, the mean stress, and the alternating stress. Also compute the stress ratio, R$.$ The length $L$ is $75$ mm $.$ The dimensions of the spring cross section are $t=0\mathrm{.}85mm$ and $b=5\mathrm{.}0$ mm $.$

$($c$)$ Pictorial view of cam, follower, and spring

Total excursion of follower $=5\mathrm{.}0mm$ during one revolution

$($b$)$ Cross section of spring $($enlarged$)$
