If you're designing a system for hoisting a load using a pulley and a motorized winding drum, you must space the drum and the pulley sheave apart far enough to maintain a safe "fleet angle." The fleet angle of a sheave-and-drum pulley system refers to the maximum angle from the front of a fixed sheave to the outermost position along the drum as it winds the fiber (e.g., rope, cable or wire). If the angle is too small, you'll won't be able to wind enough fiber for the system to be useful; if the angle is too large, the fiber will be pulled off the sheave's track, requiring you to shut down and repair the system.. 1 Measure the direct distance from the front of the fixed sheave to the axis of the drum (in feet).2 Measure the length of the smooth-faced drum from the center to the left edge (in feet).3 Divide the result from Step 2 by the result from Step 1. 4 Calculate the arctangent of the result from Step 3. This is the left fleet angle of the drum.5 Measure the length of the smooth-faced drum from the center to the right edge (in feet).6 Divide the result from Step 5 by the result from Step 1.7 Calculate the arctangent of the result from Step 6. This is the right fleet angle of the drum.

Drum percussion is so loud because of the oscillations of the drum surface. The oscillation of drum surface causes oscillation of air molecules and loud noise.

The price of a 280 liter drum of chloroform can vary depending on the supplier and market conditions. It is best to contact suppliers directly for current pricing information.

It is the surface of the drum shell that actually touches the drum head. The area of this surface is less than that of a cross-section of the whole shell, since it is created by making an angled cut into the shell around the rim. The thickness or thinness of the bearing edge affects the tone of the drum; finer or sharper bearing edges yield a brighter tone, while thicker bearing edges yield a warmer tone. If the bearing edge is not perfectly level and perpendicular to the cylinder of the shell, the drum head will not seat properly and the tone of the drum will suffer.
