What is the difference between shaft and rod?
ANY MACHINED BAR CAN BE CALLED AS ROD, IT TRANSFERRS MOTION FROM ONE LINK TO ANOTHER..................IF THE SUPPLIED MOTION IS OF TORSIONAL TYPE(WHICH TENDS TO ROTATE THE LINK ON ITS OWN AXIS) THE SAME ROD IS CALLED A SHAFT... RANA PRAKASH ranaprakash2873@gmail.com
What is torsion testing machine?
A torsion testing machine is used for determining the shear stress, modulus of rigidity, strain energy, ultimate torsional stress, etc of a material. It is mainly used in the field of Mechanical Engineering. The machine consists of two jaws. One jaw is capable of rotating whereas the other jaw remains stationary. The movable jaw is driven by an electric motor which can be operated in both forward and reverse directions.

What is the torsional rigidity of a shaft?
It is defined as ratio of the product of modulus of rigidity and polar moment of inertia to the length of the shaft. Torsional Rigidity is caluclated as: Torsional Rigidity= C J/l
Torsional rigidity of a solid circular shaft of diameter d is proportional to?
inversly proportioal to cube of diameter
What is difference between torsional rigidity and lateral rigidity?
The torsional rigidity comes from the torso. The lateral rigidity would come from the arms and the legs becoming stiff.
What is torsional pressure?
Force exerted from a rope tide around the catapult shaft
How can one convert between Newton meter by degree and Megapascal as units of torsional rigidity?
One pascal is 1newton/meter^2. Therefore one megapascal is 10^6 newton/meter^2. Megapascal is a unit of Pressure (to be precise, stress) . So we cannot convert between Newton meter per degree and Megapascal as units of torsional rigidity.
Is torsional critical speed the same as torsional Analysis?
Torsional analysis: This analysis completed based on strcture properties like Mass MI and Torsional stiffness. Torsional critical speed analysis: Speed of rotor will come into picture in addition to Mass MI and Torsional stiffness of the structure.
What is torsional oscillation?
Torsion = turning Oscillation = repeated motion toraion oscillation is repeated turing back and forth. Imagine you have a weight hanging on the end of a piece of string. Twist the weight and, when released, it will oscillate torsionally.
What effect has a keyway on the strength of a shaft?
1. This is due to the stress concentration at the corners of the key way and reduction in the cross-sectional area of the shaft. It, other words the torsional strength of the shaft is reduced. 2. In case the key way is too long and the key is of sliding type, then the angle of twist increased. So it is actually assumed that the strength of the keyed shaft is 75% of the solid shaft.

What is torsional critical speed?
The term torsional critical speed of centrifugal pumps and associated drive equipment refers to the speed of a pump rotor or related rotating system that corresponds to a resonant frequency of torsional vibration of the rotating system. Torsional critical speeds are associated with torsional or angular deflection of the rotor and are not to be confused with lateral critical speeds associated with lateral deflection. The two are separate entities. A given rotor or rotating system may possess more than one torsional resonant frequency or torsional critical speed. The lowest frequency which produces the "first mode shape" and "first torsional critical speed" is in general of the most concern. Torsional vibration is caused by torsional excitation from sources such as variable frequency drive motor toque pulsations, combustion engine torque spikes and impeller vane pass pulsation. The calculation of the first torsional critical speed is fairly simple for simple rotor systems.
What Torsional force?
a colloquialism
what is a torsional stress?
The torsional stress refers to the stress that arises from the deformation set up by a twisting moment or torque.
