To calculate the center of gravity for a taper shaft, you would need to consider the varying cross-sectional area along the length of the shaft. You can use an integral approach to determine the centroid of each cross-sectional area and then calculate the weighted average of these centroids to determine the overall center of gravity of the taper shaft. Alternatively, you can simplify the taper shaft as a series of smaller sections with uniform cross-sections and calculate the center of gravity for each section, then determine the overall center of gravity using the weighted average of these section centroids.

To use a taper lever on a clipper or trimmer, simply adjust the lever to the desired position to change the cutting length. Move the lever upwards for a shorter cut and downwards for a longer cut. This allows you to easily blend and transition between different cutting lengths.
B. Minor scoring. Machining a brake drum may not be necessary if there is only minor scoring present. Taper, out-of-roundness, and pulsation are all reasons to consider machining a brake drum to restore its smooth surface and proper functionality.
To fit a 16 gauge earring into an 18 gauge piercing, you'll need to stretch the piercing slowly and carefully using tapers or gradually increasing the size of the jewelry over time. It's important to allow enough healing time between stretches to prevent irritation or damage to the piercing. Consulting a professional piercer for guidance and assistance is recommended for this process.
Using a smouldering rag or taper helps to visualize convection in air because the rising smoke from the smouldering material provides a visible indication of the movement of air currents. As the hot smoke rises, it demonstrates how warm air is less dense and more buoyant, causing it to move upwards in the convection process. This can help observers see the motion and direction of the air flow in a natural and easy-to-follow manner.
Power is transferred from the drill spindle to the drill shank through the rotation of the spindle, which is connected to the motor. As the spindle rotates, it drives the drill bit, which is inserted into the drill shank. The force and torque generated by the spinning spindle are then transmitted through the drill bit to the workpiece, allowing for drilling to occur.
