Figure 1 shows the shaft assembly of a grinder, with an abrasive wheel at each end and a belt-driven sheave at the center. When turning at 3000 rpm, the smaller abrasive wheel is accidentally jammed, causing it to stop \"instantly.\" Estimate the resulting maximum torsional stress and deflection of the shaft. Consider the abrasive wheels as solid disks of density p = 2000 kg/m3. The shaft is steel (G = 79 GPa), and its weight may be neglected.

Solution

maximum torsional will be 79*2000 = 158000
