A motorcycle and rider have a combined mass of 350kg. The vehicle's velocity is 100 km/hr. The rider is to go up a hill incline of 10 meters. The wheels each have a mass of 20 kg and a diameter of 500mm. The wheel design consists of 6 spokes with a mass of 0.5 kg for each spoke. a. Determine the vehicle's velocity at the top of the hill, assuming it was a rolling vehicle with engine being turned off. a. Indicate the vehicle's velocity at each meter through the climb. b. Explain the transfer energy and how this affects the behaviour of the system. At another point in its journey, the motorcycle and rider travel at 80 km/h around a left-hand bend of radius 30m. Calculate: a) The angular velocity of each wheel. b) The moment of inertia of each wheel. c) The angular momentum of the wheel prior to entering the bend. d) The magnitude of the gyroscopic torque produced on the bike as the rider is driving around the bend. What is the effect and why is it important to calculate the gyroscopic…
roblem 2 The forked rod is used to move the smooth 2-lb particle around the horizontal path in the shape of a limacon, ? = (2 + 2????) ft. If at all times ?̇ = 0.8 rad/s, determine the force which the rod exerts on the particle at the instant ? = 30°. The fork and path contact the particle on one side only please explain the steps
The mass B is attached to the arm that rotates in the horizontal planeabout a pin in collar A. A motor in A keeps the angular speed of the arm constant at ˙ θ = 2.4 rad/s. Determine the velocity and acceleration of A as functions of the angle θ. Assume that vA = 0 when θ = 0. Friction and the mass of the rotating arm can be neglected.

The small body has a speed VA = 6.2 m/s at point A. Neglecting friction, determine its speed at point B after it has risen 1.51 m. Is knowledge of the shape of the track necessary? + 1.51 m Answer: VB = i 6.2 m/s A m/s B
Show that the girl at A can throw the ball to the boy at B by launching it at equal angles measured up or down from a 45° inclination. If vA = 10 m/s, determine the range R if this value is 15°, i.e., 0, = 45° – 15° = 30° and 02 = 45° + 15° = 60°. Assume the ball is caught at the same elevation from which it is thrown. II VA = 10 m/s A B
