Based on Figure Q4(a), the diaphragm in a differential pressure gauge deflects proportionally with the pressure difference across it. This deflection is used to measure the pressure difference, QR. To operate well, the material must not fail under the loading, and it should have a large deflection in order to increase the sensitivity of the measurement. The equations below for maximum stress and of a circular diaphragm of fixed radius are important to answer this question. The diaphragm thickness is t, E is Young's Modulus, and v is Poisson's ratio.

Two blocks are connected by an ideal string, which passes over a pulley without slipping (see figure). The magnitudes of the wire voltages applied to blocks 1 and 2 are represented, respectively, by T1 and T2. Consider T2>T1. In this case, the pulley rotates counterclockwise. The pulley has radius R=0.10 m and rotates around an axis perpendicular to its surface passing through its CM. The CM of the pulley coincides with its center. The pulley's moment of inertia about the axis of rotation is denoted by I and its angular acceleration is α=0.50 rad/s2. If T2=87 N and T1=50 N, determine I (in kg⋅m2).
