1 out of A wheel has an inner radius Ry = 0.5 m and an outer radius R2 = 1 m. The wheel is able to rotate around an axis that passes through its center and perpendicular to its plane. Two forces F = 20 N and F2 = 8 N act on the wheel as shown in the figure below. The magnitude of the net torque (in N.m) acting on the wheel about the rotation axis is: →F2 a)...

Question 4 [25 marks] An electric motor drives a coaxial rotor through a single-plate clutch which has two pairs of driving surfaces each 300 mm external and 175 mm internal diameter. The variation of normal pressure with radius is given by a + b/r Pa and the maximum pressure is 150 kPa. The spring force on the system is 500 N. The mass of the motor armature and shaft is 750 kg and its radius of gyration is 240 mm;...

Suppose that we have an axon that is 10 cm long, with an inner radius r1 of 1 μm and outer radius r2 = r1+ 1nm = 1 μm + 1nm. In this exercise, you may use a dielectric constant for cellular fluid of κ = 3. Write an expression for the magnitude of the Electric Field, “E” outside (at an arbitrary radius r) for a uniformly charged cylinder of length “l” with charge “q”: This cylinder is in a...
