Estimate what is the mass of the wheel

Reference no: EM13654327

A wheel is made of two solid metal disks glued together. Thecombined moment of inertia of the wheel is 452 kg-m^2. thediameters of the disks are 1.2m and 0.8m. The thicknesses are 20 cm(lg diameter) and 40 cm.

a) What is the mass of the wheel (both disks are made of the samemetal)?

b) If another wheel had the same dimensions, but made of aluminum,what force would be required to lift it off the bottom of a lakethat was 14 feet deep at 40 degrees N latitude at noontime?
