How does testicular torsion happen?
How does testicular torsion happen?
Testicular torsion occurs when a testicle rotates, twisting the spermatic cord that brings blood to the scrotum. The reduced blood flow causes sudden and often severe pain and swelling. Testicular torsion is most common between ages 12 and 18, but it can occur at any age, even before birth.
What is another word for torsion?
In this page you can discover 13 synonyms, antonyms, idiomatic expressions, and related words for torsion, like: torque, tortuosity, tortuousness, contortion, crookedness, torsional, axial, transverse, curvature, dihedral and null.
What do you mean by torsion?
In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Torsion is expressed in either the Pascal (Pa), an SI unit for newtons per square metre, or in pounds per square inch (psi) while torque is expressed in newton metres (N·m) or foot-pound force (ft·lbf).
How do you use torsion in a sentence?
Torsion in a Sentence 🔉
- “
- The torsion of the two wires together allowed the man to double the size of the wire as he pulled on either end.
- Instead of hammering a nail straight into the piece of wood, a screw would be better since it has its torsion at one end of the screw.
What is torsional moment?
Torsion is the twisting of a beam under the action of a torque (twisting moment). In the case of a torque, the force is tangential and the distance is the radial distance between this tangent and the axis of rotation.
What is torsion theory?
If a material is subjected to twisting by the application of a couple a shear stress will be induced within the material. If a couple is applied to a cylindrical rod in such a way that the axis of the couple is coincident with the axis of the rod, then the rod is said to be subject to pure torsion.
What is torsional rigidity of a wire?
Torsion is the twisting of an object due to applied torque. A torsion pendulum is an oscillator for which the restoring force is torsion. Rigidity modulus or shear modulus is the ratio of shear stress to the displacement per unit sample length.
Which material is suitable for shaft material?
steel
What is the difference between torsional rigidity and rigidity modulus?
Torsional Rigidity : The Angle of Twist per unit length of the Shaft. In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Rigidity is the maximum resistance an object can offer before it deforms, in other words, it is the minimum force required to deform an object.
When a shaft is subjected to pure twisting then the type of stress developed is?
Explanation: Shear stress is produced when the shaft is subjected to pure twisting (torsion). The shear stress due to twisting moment is zero at the axis of the shaft. Explanation: The product of shear modulus(C) and polar moment of inertia (J) is called torsional rigidity.
What is the other name for a positive bending moment?
Explanation: The bending moment at a section is considered to be positive when it causes convexity downwards such bending moment is called sagging bending moment positive bending moment.
What is J in shear stress?
τ = shear stress (N/m2, Pa) T = applied torque (Nm) r = distance along radius of shaft (m) J = polar moment of inertia (m4) When shear stress is being measured at the outer edge of the shaft, the letter “c” is sometimes used in place of “r” to indicate that the radius is at its maximum.
Is used to support the rotating shaft and confine its motion?
What is the function of bearing? Ans: To support the rotating shaft and confine its motion.
Which type of joints is better when the product is subjected to large vibrations welded or threaded?
Which type of joints is better when the product is subjected to large vibrations: welded or threaded? Explanation: Threaded joints loosen when subjected to vibrations. Explanation: Bolt is threaded into a nut while screw is threaded into a tapped hole. 4.
Is used for a shaft that supports rotating elements like wheel drum or rope sleeves?

- The next number is the rivet diameter:
What do the markings on the heads of solid shank rivets indicate?
