rotational motion stabilization for a vertical shaft

Experiments of Mechanical Vibration Laboratory

2015-3-27This block can be moved along a guide to change the effective length of the shaft which passes through both chucks to produce the rotational flexibility For the part of damped vibration there is a vertical shaft gripped at its upper end by a chuck attached to a bracket K1 while its lower end is attached to a heavy wheel K3 with conical lower

The anterior cruciate ligament-deficient (ACLD) knee requires appropriate treatment for the patient to return to sports The purpose of this study was to clarify the kinematics of the anterior cruciate ligament-deficient knee in squatting motion before and after double-bundle anterior cruciate ligament reconstruction (DB-ACLR) using a 2D/3D registration technique

Torque with Examples

2020-8-20TORQUE We define torque as the capability of rotating objects around a fixed axis In other words it is the multiplication of force and the shortest distance between application point of force and the fixed axis From the definition you can also infer that torque is a vector quantity both having direction and magnitude However since it is rotating around a fixed axis its direction can be

Nonlinear theoretical analysis of contacting forward

2013-5-27A disk was fixed at l ^ 1 = 208 mm from the top of the vertical rigid rotor and its radius was 8 mm its length was 356 mm The shaft and the disk were made of stainless steel The upper end of the rotor shaft was supported by a self-aligning ball bearing (#1200) and the lower end was supported by the magnetic repulsive force between permanent
