probably to give good location to drill ( angle120 degrees)
Typically a center punch tool is used to aid in drilling. The impression made by a center punch into wood, plastic or metal marks the area to be drilled and helps the drill stay on course as it goes through the material. The traditional center punch is used with a hammer and the automatic center punch uses a spring tension mechanism to create a force hard enough to make the indentation. Read on to learn how to use a center punch.
offset that are not situated 90 degree rather that are situated in any angle like 60 degree or 45 degree
Rotational 90 degree asists.
A V6 90-degree engine refers to a six-cylinder engine with two banks of three cylinders arranged in a V shape, creating a 90-degree angle between the banks. This configuration allows for a more compact design while providing a good balance of power and smooth operation. The 90-degree angle helps minimize vibrations and can contribute to a more refined engine performance compared to other V configurations.
90 degrees
The angle of a center punch typically ranges between 90 to 120 degrees. This angle helps create a sharp point that effectively marks the surface, allowing for precise drilling. A common design is a 90-degree angle, providing a good balance between durability and marking effectiveness.
How to calculate 90 degree and 40 degree elbow center >For 90 degree elbow(Dia*38.1) this formula used for only 90 degree elbow. >For 45 degree elbow(45/2of tan*Dia*1.5*25.4) this answer obtained in (mm).

Formula for calculating center to end distance of such elbows is as follows: For 90° Long Radius elbows, center to end dimension given in dimension tables of ASME B16.9 is same as radius of elbow. This is because Tan (90/2) i.e. Tan 45 is 1. Normally custom elbow angles from 45 degree to 90 are cut from 90 degree standard elbow. If that's what you were asking about...
You hit as hard as you can and tighten your index, middle, and ring finger. You also bend your thumb over your index & middle finger at about a 90 degree angle.
