Pulley. Function of Pulley. The function of a pulley is to lift heavy objects by changing the direction of the force on a flexible cable. It also consists a wheel with a groove in its outer edge and an axle. With the help of ropes, chains or cords, a pulley makes moving objects upward easier. Pulley reduces the force given to get the work done.

Pulley should be large enough to avoid to hard bend at point of tension application Pulley should have grab - risk of slippage is function of grab and tension - more grab - less tension - could mean a cheaper belt Place Drive in practical location to minimize the highest tension in the belt - a head pulley location often good on a belt up a slope

The role of the long head of the biceps muscle (LHBM) and its proximal tendon (LHBT) within the glenohumeral joint remains unknown. Various authors have proposed that the LHBT may play a role in glenohumeral stability, 5,6,10,12 humeral head depression, 15 and overall glenohumeral kinematics. 14 These studies suggest that efforts should be made to preserve the LHBT in cases of …

The force table uses pulleys, strings, and weights placed around a circular table. Weights are placed at the end of strings supported by pulleys located on a circular tabletop. When equal amounts of weight (or force) are added the string will find equilibrium and acceleration in a certain direction will halt.

The pulley in contact with the belt has a diameter of 8" and a coefficient of static friction of 0.30. Determine the tension in each part of the belt if the belt is not to slip and: the system uses a flat belt the system uses a V-belt with a 38o V and the same coefficient of friction 40o 60o

The mechanical advantage of a movable pulley (one where the pulley can move freely along the rope) is two Example. The 10 N load below would still require 10 N of force to lift as the extra pulley ...

Power transmission is a function of belt tension. However, also increasing with tension is stress (load) on the belt and bearings. Belt tensions should also be adjusted to belt type, size, speed, and pulley diameters and when your tensioners and pulleys get worn, then it is time to replace them in order to keep your belt tension at optimum levels.

Drive/Head Pulley – A conveyor pulley used for the purpose of driving a conveyor belt. Typically mounted in external bearings and driven by an external drive source. Idler Pulley – Any pulley used in a non-drive position that is intended to rotate freely and be driven by the belt.

Drill press parts diagram better explain the functions performed as every part of the drill press has a unique and separate function. The parts of the drill press include head, sleeve, spindle, column, table and base. Following are some of the parts of the drill press along with their functions: Head

Structure and Function. Trochlea is Latin for pulley, which appropriately describes the sling of connective tissue that houses the tendon of the superior oblique. Moreover, the trochlear nerve is a somatic efferent (motor) nerve, and along with oculomotor (III) and abducens (VI) nuclei, it is responsible for eye movement.
