Striking the arc only on the weld joint ensures that the heat is concentrated at the intended welding area, preventing damage to the surrounding material. This helps create a strong and consistent weld while minimizing the risk of overheating and distortion in the base metal.

How are the pivot joint and ball and socket joint different?

A pivot joint allows rotation around a single axis, like the rotation of the forearm. A ball and socket joint allows for movement in multiple directions, such as the shoulder joint which can move in all directions.


Why is the shoulder joint harder to move than the elbow joint?

The shoulder joint is not harder to move, it just moves differently. It is a ball and socket joint, giving it a wider range of movement, but the elbow is a synovial joint, which can only move in one direction. The reason that yo may find it harder to move your shoulder is because the muscles pulling it may be less developed and also it has to pull up an entire arm, not just a forearm.


What is the difference between struck and hit?

Difference between hit and strike: 'Strike' and 'hit' both momentum, different masses different velocities, overall same deal except a car hits you and a snake strikes you. Hit: Strike with a blow or a missile of a moving body example is the plane hit the ground or hit the window with the ball. Strike: an attack especially from the air. You can 'hit' the ball with the bat, or if you swing and miss, it is a 'strike'. 'Strike' is longer You 'hit' or miss, but you only 'strike' and never unstrike. 'Hit' is when a movie makes it big and 'strike' is when the union employees would not work. Hope it helps :) 'Hit' is nothing but it is a word. For example if you want to hit a ball means you should use more energy but when we come to strike in the game caroms, we should strike the carom coins, meaning less energy is applicable for this purpose It all depends on the context or how one uses the word in a sentence. English language is quite confusing and most words have multiple meanings. You can hit or strike a person And you can take a hit off a cigarette but not strike. You can strike a match but not hit it. You can hit a ball, but if you miss it you have taken a strike.


Do all light waves that strike a convex lens pass through the focal point?

No, not all light waves that strike a convex lens pass through the focal point. Light waves that are parallel to the principal axis will pass through the focal point after refraction, while light waves that strike the lens at different angles will converge at different points along the focal plane.


What is the only movable bone in the facial skeleton?

The mandible, also known as the jaw bone, is the only movable bone in the facial skeleton. It is attached to the skull by the temporomandibular joint, allowing for movements such as chewing and speaking.
