Luckily, there are medicines, called antacids, which can help relieve heartburn pain. Antacids essentially work by increasing the pH of the very acidic stomach acid. They don't need to raise the stomach acid pH all the way to a neutral pH of 7, but just raising the pH to 3 or 4 will make a person feel better.
Calculate the AMA of the ramp below. Show your work. 6. The efficiency of a machine can be determined by the following equation. efficiency = actual mechanical advantage x 100 OR (Work Out) / (Work In) x 100 ideal mechanical advantage efficiency = AMA x 100 IMA 6a. Determine the efficiency based on the diagram below. Show work.
Mechanical efficiency. Mechanical efficiency, measure of the effectiveness with which a mechanical system performs. It is usually the ratio of the power delivered by a mechanical system to the power supplied to it, and, because of friction, this efficiency is always less than one. For simple machines, such as the lever and the jackscrew, the efficiency is the actual load lifted divided by the theoretical force delivered.
