Problem $2$: $($from $5-3)$ For the bicycle pedal arm assembly in Figure P$5-1$ with a rider$-$applied force of $1500$ N at the $[$center of the$]$ pedal, determine the $[$maximum$]$ von Mises stress in the $15-$mm$-$dia $[$solid and round$])$ pedal arm. $[$Assume static analysis, as if something is preventing the pedal from tuming.$]$ Find the safety factor against static faflure if the material has $S_y=350$MPa. $($Use the Distortion Energy failure theory; if the von Mises stress is greater than $S_y,$ then the safety factor will be less than $1.]$
