Answer #1

Shear strength of plate = 400 MPa

plate is 400 mm wide and 0.03 mm thick.

Diameter of fllywheel = 1000 mm ; radius = 500 mm = 0.5 m

Let M = mass of flywheel. (Kg)

A 4-mm thick, 20cm diameter cast iron frying pan (K = 55 W/mK) is used on an induction stovetop. Induction stovetops work by creating a dynamic magnetic field in the pan, thereby resulting in energy being generated inside the pan material itself. The induction stovetop surface is made from a glass-ceramic material, which has a very low thermal conductivity, and consequently the bottom surface of the pan may be considered as perfectly insulated during operation. For a given stovetop setting,...
