WebTransport across membranes All cells are enclosed by a cell membrane, which is selectively permeable. Molecules can move into or out of cells by diffusion and active transport. Cells... WebA solid shaft and a hollow shaft are made of the same material and are of the same weight and length. Denoting by n the ratio c₁/c₂, show that the ratio Tₛ/Tₕ of the torque Tₛ in the solid shaft to the torque Tₕ in the hollow shaft is (a) √(1 - n²)/(1 + n²) if the maximum shearing stress is the same in each shaft, (b) (1 - n²)/(1 + n²) if the angle of twist is the same for ...
