This is an interesting phenomenon, and a very difficult one to explain. Both torque and angular momentum must be treated as vectors. Torque causes angular momentum to change according to the following equation: delta L rightarrow = rightarrow delta T To use this equation the direction of a torque vector must be defined. Follow the moment arm with the fingers of your right hand. Then turn your fingers to follow the force. As you do this, your thumb will point...

17. [1pt) A wheel of mass m = 1.87 kg and moment of inertia, I = 1.530 kg.m- is supported by a pivot a distance d=0.17 m from the wheel, as shown in the diagram. The axle through the wheel is initially in the horizontal plane, as shown, and the wheel is spinning about the axis in the sense indicated, with an angular velocity o = 90 rad's. Answer the following three questions using the choices given; c.g., if the...

A bicycle wheel has four firecrackers attached to it on opposite ends of the wheel's diameter, as shown in the figure to the right. When the firecrackers are lit, they release heated gas away from their front ends. The bicycle wheel is pivoted against a wall by its center of mass and is free to spin. a. Which way will the bicycle wheel spin when the firecrackers are lit? Explain using the torque right hand rule. b. What is the...

need to know these two angular momentum and torque questions
19.) A wheel is designed by placing two thin rods, each with a mass of 20 kg and a length of 3.0m, inside a thin ring with a mass of 10 kg and a radius of 1.5m. A small point mass of 1.0kg is attached to one of the thin rods at 0.75m from the center. 1.5m a.) b.) Calculate the total moment of inertia of this wheel. The wheel...

Up A #4. [Gyroscope Wheel] A rubber wheel on a steel rim spins freely on a horizontal axle that is suspended by a fixed pivot at point P. When the wheel spins at a rate of 4.00 rev / s, it precesses smoothly about point Pin a horizontal plane with a period of 3.50 s. The wheel's outer radius is 15.0 cm, and it's total mass is measured to be 1.12 kg, 60% of this being the spinning wheel and...

1. The drive components of a two-speed bicycle are constructed as follows: • The rear wheel has a radius of 50 cm • The front gear has a radius of 10 cm, and is connected to the pedals • There are two rear gears: one with a radius of 5 cm (“high gear”), and one with a radius of 10 cm (“low gear”) • A chain connects the front gear to one of the rear gears; the cyclist can choose...
