When a large amount of power is to be transmitted over long distances from one pulley to another (i.e. when the pulleys are up to 150 meters apart), then wire ropes are used. The wire ropes are widely used in elevators, mine hoists, cranes, conveyors, hauling devices, and suspension bridges. The wire ropes run on […]

Wire rope comes under the Rope drives. The rope drives are widely used where a large amount of power is to be transmitted, from one pulley to another, over a considerable distance. It may be noted that the use of flat belts is limited for the transmission of moderate power from one pulley to another […]

The rope drives are widely used where a large amount of power is to be transmitted, from one pulley to another, over a considerable distance. It may be noted that the use of flat belts is limited for the transmission of moderate power from one pulley to another when the two pulleys are not more […]

We have already discussed that a V-belt is mostly used in factories and workshops where a great amount of power is to be transmitted from one pulley to another when the two pulleys are very near to each other. Let us discuss more details on the V-Belt Drives and Pulleys. The V-belts are made of fabric and […]

The pulleys are used to transmit power from one shaft to another by means of flat belts, V-belts, or ropes. Since the velocity ratio is the inverse ratio of the diameters of driving and driven pulleys, the pulley diameters should be carefully selected in order to have the desired velocity ratio. Let us discuss the Design […]

Since the velocity ratio is the inverse ratio of the diameters of driving and driven pulleys, the pulley diameters should be carefully selected in order to have the desired velocity ratio. Let us discuss Different […]

The belts or ropes are used to transmit power from one shaft to another by means of pulleys that rotate at the same speed or at different speeds. The material used for belts and ropes must be strong, flexible, and durable. It must have a high coefficient of friction. Let us see How we can calculate Power […]

Belt drives are integral components of many mechanical systems and understanding their operation is pivotal, particularly the phenomenon of belt slip. This comprehensive exploration dives into the complex world of belt drive systems, delving into the functionality of individual components, with a special concentration on belt slip. Belt slip, an occasional inevitable occurrence, often impacts the […]

The belts or ropes are used to transmit power from one shaft to another by means of pulleys that rotate at the same speed or at different speeds. The material used for belts and ropes must be strong, flexible, and durable. It must have a high coefficient of friction. There are 3 types of belts, Flat belts […]

The power screws (also known as translation screws) are used to convert rotary motion into translatory motion. For example, in the case of the lead screw of lathe, the rotary motion is available but the tool has to be advanced in the direction of the cut against the cutting resistance of the material. Let us discuss the […]

Among the basic components of an Internal Combustion engine, the Connecting Rod for IC Engine is the most critical. The connecting rod is subjected to alternating direct compressive and tensile forces. Since the compressive forces are much higher than the tensile forces, therefore the cross-section of the connecting rod is designed as a strut and Rankine’s formula is used. […]

Among the basic components of an Internal Combustion engine, the Connecting Rod for IC Engine is the most important and critical. The connecting rod is subjected to alternating direct compressive and tensile forces. Since the compressive forces are much higher than the tensile forces, therefore the cross-section of the connecting rod is designed as a strut and […]

Among the basic components of an Internal Combustion engine, the Push rod is one of the critical components. The push rods are used in overhead valve and side valve engines. Since these are designed as long columns, therefore Euler’s formula should be used. The push rods may be treated as pin-end columns because they use spherical […]

Among the basic components of an Internal Combustion engine, the Piston rod is one of the most critical components. Since this Piston rod moves forward and backward in the engine cylinder, it is subjected to alternate tensile and compressive forces. It is usually made of mild steel. One end of the piston rod is secured […]

A machine part subjected to an axial compressive force is called a strut. A strut may be horizontal, inclined, or even vertical. But a vertical strut is a column, pillar, or stanchion. The machine members that must be investigated for column action are piston rods, valve push rods, connecting rods, screw jack, side links of toggle jack, etc. We discussed Euler’s […]

Usually, it is a common phenomenon observed in long columns failure due to buckling load and the short columns usually fail due to crushing load. The Rankine-Gordon formula assumes a combined failure mode which is combined buckling and crushing loads in columns. This common mode is known as the Rankine formula for columns. Hence, we […]
