If we consider the friction or screw jacks used to lift a vehicle to change a flat, almost all of those are made entirely of metal (steel). In the case of hydraulic jacks, they are made largely of steel, and have rubber for seals and hydraulic fluid to provide the media to perform the hydraulic work.

What is meant by grade of a threaded fastener?
A grade denotes the mechanical properties of a screw - the materials used, size, direction of the thread and so on.
What happens if oils are used insteat of water in hydraulic jacks?
Most jacks use oil and not water so nothing adverse would happen.
Can any one of you please suggest which materials are to be prepared for basic mechanical engineering?
First you have talent. Mathematics. Physics. Materials science. Static. Strength of Materials. Technical drawing.
What is the difference between mechanical stress and thermodynamic stress?
Mechanical stress is due to the resistance offered by various materials against physical distortion or damage. Thermal stress is caused due to the expansion of materials due to the variations in temperature with respect to reference value.

What's the advantage of air jacks over mechanical jacks?
Air jacks offer a stronger lift than mechinical jacks. They also give you the ability not have to manully crank the jack.
What materials did the first mechanical clock used?
The first mechanical clocks used materials such as iron, brass, wood, and lead for their construction. These clocks also incorporated features like weights, gears, and escapements to regulate timekeeping.
Bones used in jumping jacks?
Bones used in jumping jacks will be the bones of the arms and legs. The extremities will move when jumping jacks are done.
What does ratcheted mean?
A ratchet is a mechanical device that can rotate back and forth with the action of a cam or ball. This is much used in wrenches, jacks, come-alongs etc.
WhatImportance of mechanical metallurgy to material and metallurgical engineering?
it is used to know and improve the quality of materials.
What are photoelastic materials?
Photoelastic materials are transparent materials that change their optical properties when subjected to mechanical stress. When stress is applied, these materials exhibit a birefringence effect, which causes them to change colors or patterns under polarized light. They are commonly used in stress analysis and to visualize stress distributions in mechanical components.
Are Walker hydraulic jacks still made?
NAPA used to sell Walker jacks, check with them.

Why vector calculus are used in mechanical engineering?
Mechanical engineering usually deals with forces and their effects on materials. Forces are vectors and so, to study their effects you need to use vector calculus.
