Die Stock

Die stock is expressed as the type of component which is utilized for fitting purposes while creating or shaping uniform threads on tubes, pipes, or screws. The die stock (die handle) has three screws around the adjustable part of a particular machine that helps to locate the die. Also, die stock can endure on a variety of hex and split adjustable dies of several dimensions. One of the primary reasons for using die stock in industries is because die stock can be operated by hands. Commonly, it is made up of high carbon steel.

Question

The figure below shows, at left, a solid wheel of radius R = 0.600 m and mass 70.0 kg.
Mounted directly to it and coaxial with it is a pulley with a much smaller mass and a radius of r = 0.230 m. The wheel and pulley assembly are on a frictionless axle. A belt is wrapped around the pulley and connected to an electric motor as shown on the
right. The turning motor gives the wheel and pulley a clockwise angular acceleration of 1.67 rad/s?. The tension T., in the upper (taut) segment of the belt is 165 N.
(a) What is the tension (in N) in the lower (slack) segment of the belt?
N
(b) What If? You replace the belt with a different one (one slightly longer and looser, but still tight enough that it does not sag). You again turn on the motor so that the wheel accelerates clockwise. The upper segment of the belt once again has a
tension of 165 N, but now the tension in the lower belt is exactly zero. What is the magnitude of the angular acceleration (in rad/s2)?
rad/s2

The figure shows a mass-pulley system. It consists of a pulley which is connected to the inertial frame through a frictionless revolute joint. The pulley has two sheaves, one with radius r=50 mm and the other with radius R=100mm. The sheaves are rigidly coupled together. The moment of inertia of the pulley is 1=0.03 kg m². A mass M-8 kg is suspended from the smaller sheave the pulley. A damper with damping coefficient C is connected between the mass and the inertial frame. A spring with stiffness k links the larger sheave to the inertial frame. The undamped natural frequency of the system is w₁ = 50 rad/s and the damping ratio is = 0.6. k www. 1.

Problem 8 Another Gear Two disks are connected to one another with a belt as shown. Both disks have mass m but the larger one has radius 4R and the smaller has radius R. The larger disk is powered by a motor that produces a constant torque, To, in the counter- clockwise direction. (a) By using the rotational equivalent of Newton's laws on the larger disk show that the difference in the tension at the top with the tension at the bottom is: Tto - Thot 1 4R (TO - 2m Ra), where a is the linear accleration of the elt. (b) Do the same (find Ttop - Tbot) with the smaller disk. (c) Use your two expressions to find the gular acceleration of the smaller disk. You answer should have m, R, and To in it only. (Careful, the sr aller disk does not have the same angular acceleration as the larger one).
