The difference between contraction joint and construction joint?
A construction joint in concrete jobs is a joint where a fully set and hard concrete joins a fresh concrete to make a joint. Normally, cracks would occur at this joint because concrete was not cast monolithic. A contraction joint is joint between two concrete edges so formed which allows minute movement between the two edges caused by heat or some other external forces. Usually, contraction joints are also referred to as expansion joints.
Why are railroad tracks built with a flexible expansion and contraction joint?
The tracks have a larger coefficient of linear expansion than the ground beneath.
What is the difference between pin joint and hinged joint?
in pin joint the linkages are free to move relative to one another angularly, whereas in hinge joint, one linkage is fixed and the other is free to move in angular direction.
What is meant by compression joint?
Compression joint is a term typically used in construction. It's a bell and spigot joint that becomes watertight when the spigot is pressed into a compression gasket in the bell.
What is the construction joint in water retaining structure?
The reinforced concrete construction is the construction joint in water retaining structure.
What is the type of contraction in which the muscle fibers produce increased tension but does not shorten?
An isometric contraction builds tension but there is no joint movement.

What does co-contraction mean?
Co-contraction refers to the simultaneous contraction of opposing muscle groups around a joint. This can help stabilize the joint and provide support during movements that require a high level of control and precision. However, excessive co-contraction can lead to muscle imbalances and joint dysfunction.
What is the type of muscle contraction that produces movement in a joint and allows the muscle to shorten?
By tensing.
How joint prevent expansion and contraction?
The joint doesn't prevent expansion and contraction but it limits the damage caused by thermal stress. It allows room for the concrete ( or steel ) to expand and contract without creating the severe cracks that would form without them.
What happens to your muscles when your joint is bent?
When a joint is bent, the muscles around that joint contract and shorten. This causes the joint to move, resulting in the bending or flexing of the joint. The specific muscles involved and the degree of contraction depend on the joint and the movement being performed.
What moves a joint on its axis?
A joint is moved on its axis by muscle contraction. Muscles contract to generate force, pulling on the bones that make up the joint and causing movement. The specific movement produced is determined by the type of joint and the arrangement of muscles surrounding it.
What does 'let's' mean?
Let's is a contraction meaning let us (let(u)s.)
What movement of the thigh does contraction of the gluteus maximus produce?
Contractions of the gluteus maximus muscle causes (hyper)extension of the thigh.
What can cause your hand all the way up to your elbow to shake none stop?
Mechanical Movement of Muscle Contraction and Joint
What is the travel joint in oil well completion?
it is a barrel and mandrel can move in each other to absorb expansion and contraction of the tubing.
What are different types of contraction in sport?
The different types of contraction in sport is; Concentric Eccentric you also have to include; joint action e.g. Extension / flexion the agonist / agonistic muscle pairs e.g. hamstrings, quadriceps, biceps, triceps ect. & the joint itself e.g. knee, elbow, shoulder,
