The thin L-shaped bar shown in the figure has a rotational inertia of \( 152 \mathrm{~kg}-\mathrm{m}^{2} \) about a vertical axis through point \( A \). If the forces shown are \( F 1=7 N, F 2=13.8 N, F 3=13.3 N, F 4=12 N \), and the angle \( \theta=40^{\circ} \), what is the rotational acceleration about point A caused by these forces? \[ \mathrm{rad} / \mathrm{s}^{2} \]
Expert Answer
Given values are forces F1 = 7 N F2 = 13.8 N F3 = 13.3 N F4 = 12 N Angle ?=40° moment of inertia I=152kg?m2 Let's take angular acceleration or rotatio
