Determine the forces in members AB, AC, and AD. Forces are positive if in tension, negative if in compression.

A structure consists of two thin rectangular plates having the same dimensions (shown in figure) and same mass, m = 8 kg esch. The two plates are welded together to form a rigid body that may rotate in the plane. Determine, for this rigid body, the moment of inertia ly about the fixed point P. P is frised

Select the most appropriate answer. O Bemoulli eg was derived by applying Newton's 2nd law to a particle and then integrating along a streamline: while Energy eg was derived using the 1st law of thermodynamics & consequently the Reynolds transoort theorem. Energy eg includes both mechanical.and thermal eneray, while Bernouli eg involves only.mechanical eneray. Bernoulli eg is applied by selecting two.points (can be anywhere) on a streamline (irrotational flow) and then equating terms at those points, while Energy eg is applied by selecting an inlet & on outlet sections and then equating terms at those sections. Energy eg applies to steady. incompressible. viscous flow with additional energies through the pumR. turbine, and heat engines: while Bemoulli eg applies to steady. incompressible, and inviscid flow (h = 0, a = 1). Under special circumstances, Bernoulli eg converts into Energy eg if pump or turbine added along the streamline Bernouli eg was derived by applying Newtan's 2nd law…
