Two aeroplanes with the same specification each that has an engine rotates at 2000 rpm with the moment of inertia for all rotating parts is 420 (kg)(m^2). The engine rotates anti-clockwise when viewed from the front. One of the aeroplanes turn to the left and the other turn to the right. Compare the magnitude and effect of the gyroscopic action resulting on the plane if the turning radius is 2000 m at a speed of 2000 km/h.

An electric motor exerts a constant torque of τ=10N⋅m on a grindstone mounted on its shaft; the moment of inertia of the grindstone is I=2.0kg⋅m2. If the system starts from rest, find the work done by the motor in 8.0 s and the kinetic energy at the end of this time. What was the average power delivered by the motor? Part A:Suppose we now turn off the motor and apply a brake to bring the grindstone from its greatest angular...

HW Problem 5: A 150 kW motor drives a hollow round shaft at 1,200 rpm. The outer diameter of the shaft is 100-mm and the inner diameter is 0.95*outer diameter. It is made of AISI 1050 WQ&T at 425- deg C. (a) Look online or the book and explain briefly what “WQ&T” in the material designation stand for, and how it is different than OQ&T. Which is stronger at the specified temperature? (b) Determine the maximum torsional shear stress (Tau...

A 1.5 kg , 20-cm-diameter turntable rotates at 50 rpm on frictionless bearings. Two 470 g blocks fall from above, hit the turntable simultaneously at opposite ends of a diameter, and stick. Part A What is the turntable's angular velocity, in rpm, just after this event? Express your answer to two significant figures and include the appropriate units. w=?

A ladder rotates at a constant rate of w rad/sec as its top end slides down a vertical wall and its bottom end slides along the ground. A beetle sleeping on the ladder stays a meters from the top and b meters from the bottom. Find the speed of the beetle relative to the ground at the moment the ladder makes an angle of theta radians with the ground.

Rod OA rotates counterclockwise with a constant angular velocity of = 5 rad/s. The double collar B is pin connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod, of which the shape is described by the equation r = 1.5(2 - cos θ) ft. If both collars weigh 0.75 lb, determine the normal force which the curved rod exerts on one collar at the instant θ = 120o. Neglect...
