- Juno is a construction worker. He has found a scrap piece of construction aluminum foil. The sheet has the dimensions of 1.00ft x 5.00ft. Juno knows the 3 aluminum density is 2. 70g/cm. He weighs it and finds its mass is 20.1 grams. Help Juno figure out how thick the sheet is. write your answer in millimeters and with the correct amount of significant figures.An automobile tire is shown in the figure below. The tire is made of rubber with a uniform density of 1.10 × 103 kg/m³. The tire can be modeled as consisting of two flat sidewalls and a tread region. Each of th sidewalls has an inner radius of 16.5 cm and an outer radius of 30.5 cm as shown, and a uniform thickness of 0.675 cm. The tread region can be approximated as having a uniform thickness of 2.50 cm (that i its inner radius is 30.5 cm and outer radius is 33.0 cm as shown) and a width of 19.4 cm. What is the moment of inertia (in kg m2) of the tire about an axis perpendicular to the page through its center? " 33.0 cm 16.5 cm Sidewall 30.5 cm Tread Enter a number. find the moment of inertia of the sidewall and the moment of inertia of the tread region.
