Question $1(1$ point$)$

Given

A lever shown below has a length L$=585$mm$.$ It is attached to the shaft A using a key that has a width d and length of $29$ mm $.$ The shaft is fixed and a vertical force of $170$ N is applied perpendicular to the handle. The shaft has a radius r$=15$mm

Determine the dimension d in mm to the nearest $100$th$,$ i$.$e$.,$ two $(2)$ decimal places if the allowable shear stress for the key is $\backslash$tau $\_($all $)=37$MPa.
