A contraction joint is a sawed, formed, or tooled groove in a concrete slab that creates a weakened vertical plane. It regulates the location of the cracking caused by dimensional changes in the slab.
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.
The tracks have a larger coefficient of linear expansion than the ground beneath.
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.
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.
The reinforced concrete construction is the construction joint in water retaining structure.
An isometric contraction builds tension but there is no joint movement.

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.
By tensing.
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.
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.
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.
Let's is a contraction meaning let us (let(u)s.)
Contractions of the gluteus maximus muscle causes (hyper)extension of the thigh.
Mechanical Movement of Muscle Contraction and Joint
it is a barrel and mandrel can move in each other to absorb expansion and contraction of the tubing.
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,
