Why is a hollow shaft stronger than a solid shaft of same mass and material?

A hollow shaft is found to be stronger than a solid shaft made of equal material because the torque required to produce a given twist in hollow cylinder is greater than that required to produce in solid cylinder of same length and material through same angle.

Why are hollow cylinders stronger than solid cylinder?

Explanation: The hollow shafts can withstand the same stress as that of solid shafts. Strength to weight ratio is better for ahollow pipe than a solid rod. This means a hollow cylinder is stronger than a rod of equal mass and the same material.

Which shaft has more strength?

A hollow shaft has greater strength and stiffness than solid shaft of equal weight.

Is hollow or solid shaft better?

For the load-bearing type of shaft, it is always better to choose hollow shaft because it has higher stiffness and rigidity and can resist slightly higher bending moments. A shaft for transmission of torque like crankshafts, driveshafts, choosing a solid shaft is always better because it has higher torsional stiffness.

What are the advantages of hollow shaft over solid shaft?

Advantage of hollow shafts:

• Lightweight comparable to the solid shaft of the same diameter. Low rotational inertia.
• Less tolerant to over-torque. Prone to bending especially when exposed to lateral stress.
• Suitable for high torque applications. Very resistant to bending.
• High cost.

Is a hollow bone stronger than a solid bone?

Teacher will also explain that having a hollow center gave the bones a better design and made them stronger. Teacher will continue explaining that the large bones in our body are also hollow, which makes them strong so they can support more weight, but light, so it takes less energy to move them.

Why hollow cylinders are used in shafts?

A hollow shaft is found to be stronger than a solid shaft made of the same size and material. Reason: The torque required to produce a given twist in a hollow cylinder is greater than that required to twist a solid cylinder of the same size and material.

Is hollow shaft better than solid?

What are the advantages and disadvantages of hollow shaft over solid shaft?

Hollow shafts are much lighter than solid shafts and can transmit same torque like solid shafts of the same dimensions. Moreover less energy is necessary to acceleration and deceleration of hollow shafts. Therefore hollow shafts have great potential for use in power transmission in automotive industry.

What do you mean by strength of a shaft?

Maximum torque
Maximum torque or horse power that can be transmitted by a shaft is referred to as the strength of a shaft.

Why are bones hollow and not solid?

Often there is a jelly-like area in the centre of the bone, which is called the bone marrow. Bone marrow produces the body’s blood cells. So, bones are actually hollow tubes, a bit like bamboo which is a type of plant. A hollow structure means that the weight of the bone is a lot less than it would be if it were solid.
