The main difference between run-on torque and breakaway torque is their purpose. Run-on torque is used to maintain an object's motion, while breakaway torque is used to initiate motion. Additionally, run-on torque is typically lower than breakaway torque since less force is required to keep an object in motion compared to starting it from a ...
Hi stan. Short answer is yes. Long answer follows: Forces which resist torque on a fastener are generally broken up into 3 categories: 1. Frictional resistance at the thread. (frictional load x moment arm = torque) 2. Frictional resistance at the nut or bolt face. (frictional load x moment arm = torque) 3.
Torque is acutally a fairly poor, but easy way of specifying a certain bolt preload. This is becuase torque depends on the friction between the bolt and the nut. A high friction means that for a given torque value, you are getting less preload. Consequently if you used a lubed nut and bolt, for a given torque you'd be getting a higher preload.
511. 1. welle said: After I read that Torque is a force that is both proportional to moment arm and force applied T = f *r , I tried to explain this fact by using the concept of Work which i learned earlier. When the force F is applied perpendiculary to some point at a distance r it does work equal to W = F* (angle measure*r) or W = F* (length ...
In summary, torque is defined about a point, not specifically about an axis, but can also be calculated about an axis by taking into account the point of application of the force. This definition allows for the measurement of both the magnitude and direction of the rotation caused by a force. However, in cases where the torque is zero, it is ...
In summary, the definition of torque is the product of the distance (r) from the axis of rotation and the applied force (F). Torque can be defined in a non-rotational situation, such as when a force is applied at a distance from the axis of rotation, and the amount of torque depends on the length of the lever-arm.
Torque is a fundamental concept in engineering and physics, and can be applied in a variety of real-world scenarios. Some common applications include tightening screws and bolts, turning a steering wheel, and opening a door. Torque is also important in machines and engines, such as car engines and turbines.
Net external torque refers to the total torque acting on an object from external forces, while net torque refers to the total torque acting on an object, including both external and internal forces. Internal forces, such as the forces between different parts of an object, can cancel each other out and have no effect on the net external torque.
Homework Helper. 8,888. 649. For angular velocity, angular acceleration, or torque (angular force), one reason a vector perpendicular to the plane of rotation or torque is used because the math for vectors is simpler than trying to create math that works with rotating planes.
The pulley ratio affects torque by changing the mechanical advantage of the system. A higher pulley ratio means that the system can lift heavier loads with less force, but the trade-off is a slower speed. On the other hand, a lower pulley ratio allows for faster speed but requires more force to lift the same load.
