In some engines the lifter bore is offset in relation to the cam lobe. In others the cam lobes are tapered from side to side
So that they will rotate
Officially you should change lifters anytime you change the cam. In real world use; unless the roller lifters have obvious, visual damage, missing pins, wear on surface of the roller, then it is not normally going to be a problem. In the case of flat lifters, you should change them. The cam of flat tappet (regular) lifters, have a slight bevel to the surface of the cam. When the cam and lifter are in operation - this causes the lifters to rotate in their bore. After/during break-in, there is some wear on both surfaces and they end up with a pattern which is unique for each bore and and each cam/lifter combination. If you change either the order of the lifters on the original cam they meshed with, or install a new cam or new lifters - there is a very real chance of accelerated wear leading to failure of cam and lifter. What is worse - the resulting debris can follow the oil and ruin bearing surfaces throughout the engine. Your money, your choice.
Equipment in a generic Industrial plant setting which remain static and do not rotate during the course of operation are known as static equipment's.
Rotate friction refers to the resistance encountered when an object or component is rotated around an axis. This is commonly experienced in mechanical systems, where friction between moving parts can cause a decrease in rotational speed or make it harder to turn. Reducing rotate friction is important for efficiency and smooth operation of rotating components.
To adjust the lifters on a 1999 Honda Civic, start by removing the valve cover to access the rocker arms and lifters. Rotate the engine to bring each cylinder to the top dead center (TDC) on its compression stroke, then use a feeler gauge to check the clearance between the rocker arm and the valve stem. Adjust the clearance by loosening the lock nut and turning the adjusting screw until you achieve the specified gap, then tighten the lock nut. Repeat this process for each cylinder, ensuring you follow the correct firing order.

To rotate a shape using reflection, you would typically mirror the shape across a line (such as the x-axis, y-axis, or a custom line). The reflection operation then creates the rotated shape as a mirror image of the original shape.
Drives - I assume you are referring to Variable frequency Drives. The drives are useful when a motor needs to rotate at different speeds when in operation with out stopping it.

No, a harmonic balancer is designed to rotate in one direction only, typically clockwise when viewed from the front of the engine. It is important for the balancer to rotate smoothly and consistently in the direction of engine rotation to minimize vibrations and ensure proper engine operation.
The nosepiece holds the objective lenses in place and is able to rotate to change magnification during microscopy.
They sleep standing on one leg and rotate during the night.
