Q2. A specially designed wrench is used to twist a circular shaft by means of a square key that fits into slots (or keyways) in the shaft and wrench, as shown in the figure on the next page. The shaft has diameter d, the key has a square cross section of dimensions b x b, and the length of the key is c. The key fits half into the wrench and half into the shaft (i.e., the keyways have a depth equal to b/2). Derive a formula for the average shear stress Twg in the key when a load P is applied at distance L from the center of the shaft. Draw the free body diagram.
