What is torsional pressure?
Force exerted from a rope tide around the catapult shaft
What is a force trying to twist a structure called?
A force trying to twist a structure is often referred to as torsional force. This force creates a twisting motion in the structure, causing it to deform and potentially lead to failure if not properly accounted for in the design. Torsional forces are common in structures subjected to loads that produce rotational or twisting effects.
Does the torsional pendulum depend on acceleration due to gravity?
Yes, the period of a torsional pendulum does depend on the acceleration due to gravity. The period is given by the formula T = 2Ïâ(I/Îș), where I is the moment of inertia and Îș is the torsional spring constant, and both of these factors are influenced by gravity.
Is torsional critical speed the same as torsional Analysis?
No, torsional critical speed is the rotational speed at which a rotating shaft exhibits excessive deformation or failure due to resonance. Torsional analysis, on the other hand, involves studying the torsional behavior of a system to ensure it can withstand the applied torsional loads without experiencing failure.
In a torsion catapult what are the forces that act upon it?
In a torsion catapult, the main forces that act upon it are the torsional force applied to the twisted rope or spring when it is released, the gravitational force pulling the projectile downward, and air resistance opposing the motion of the projectile through the air. The torsional force causes the arm of the catapult to rotate and launch the projectile forward.
What is torsional force?
"Torsional strain" is the strain induced by applying torque. Basically, it is the strain imposed on a body by twisting it. (Such as the strain that a bolt endures when you use a wrench on it.)
How did coulomb measure the force between electric charge?
Coulomb used a torsion balance to measure the force between electric charges. He noted that the force between charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. Coulomb's law quantifies this relationship, providing a mathematical expression for the force between charges.
What type of force act when you twist wet clothes to squeeze out water?
When you twist wet clothes to squeeze out water, you are applying a torsional force. This force causes the fibers of the fabric to deform and release the water trapped within them.
What is 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
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.
How do you calculate braking torque?
To calculate brake torque, multiply force with the distance from the point of rotation. Force is equal to the torsional reaction caused by the brakes, and is also equal in magnitude to the torque exerted by the road.
Which type of force act when you twist wet clothes to squeeze out water?
The force acting when you twist wet clothes to squeeze out water is called torsional force. This force is generated when you apply a twisting motion to the cloth, causing the water to be forced out due to the wringing action.
