Consider the rigid rod-plus-disc system b b P Find the moment of inertia of the pendulum as it freely rotates about the point P. The rod has a length 0.65 m, and the disc has a radius half that. The pivot at P is a fourth of the way from the end of the rod. The rod has a mass of 1.41 kg and the disc is twice as massive with uniform mass distribution. Answer in units of kg · m2 .

Determine the maximum r-value of the polar equation r =3+3 cos 0

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
