Force required to move a 30000lb cart | Physics Forums

21/4/2009 · Say you wanted to move it 5m in 30seconds and it's stopped by just hitting a buffer (so you don't need any force to slow it down) The speed equation is distance = 1/2 acceleration * time^2 and F = ma. So force = mass * 2 * distance/time^2 = 6800kg * 2 *5 /30^30 = 75N or 15 lbf. Jan 30, 2009.

Rolling Resistance - an overview | ScienceDirect Topics

The types of metals in wheel and rail and the condition of wheel and rail surfaces—whether dirty or clean, wet, oily, rusted, or frosty—affect the coefficient of rolling friction. An average value for average conditions is included in gross journal resistance values as part of the residual resistance after net journal friction has been found.

9/10/2017 · Wheels can be made of a variety of materials, including polyurethane for gantry cranes, alloys, low-carbon steel, or medium-carbon steel. The more carbon in the steel, the harder the wheel will be. There are also methods of heat-treating that can be used to increase the hardness of a wheel—increasing the service life and load capacity of the wheels.
