A torus is essentially a tube wrapped into a circ le (a "doughnut" shape). The volume (V) of a torus can be calculated by
V=2 π2 R r2
where R is the radius of the torus (from the center of the "tube" to the center of the hole in the middle) and r is the radius of the tube itself. If a torus has a volume of 2537 cubic inches [in3 ] with a torus radius (R) of 0.26 meters [m], what is the radius of the tube (r) in units of centimeters [cm]?

- A motor has circular cylinders with a 3.875 inch diameter. The height of the cylinder is 4.7 inches and has an ideal gas The piston moves up in the cylinder and compresses the ideal gas. At the end of compression, the cylinder has a volume of 7.37 cubic inches The amount of gas and the temperature of the gas stay the same during compression and the initial pressure in the cylinder is 1.2 atmosphere [atm]. Find the pressure after compression in units of pounds-force per square inch [psi].arrow_forwardConsider the piston-cylinder assembly shown below. Heavy weights are added to the piston, compressing the gas. Assume that the gas reaches an internal pressure of 1.5 bar after the compression is done. The pressure outside the piston-cylinder is 1 bar. We also know that the piston diameter is 20 [cm.] With how much force doe the gas push upward on the piston (in Newtons?)
