Machinery Maintenance Calculation Formulas

What is the formula for Mechanical Advantage?

• Load X Effort

• Load / Effort

• Effort / Load

• Effort X Load

What is the formula for Mechanical Efficiency?

• ( M.A. / V.R. ) X 100%

• ( M.A. X V.R. ) X 100%

• ( V.R / M.A ) X 100%

• ( V.R X M.A ) X 100%

What is the formula for the Principle of Moments?

• Moment = Distance / Force

• Moment = Force x Distance

• Moment = Distance + Force

• Moment = Force / Distance

What is the formula used for Gear Train calculation?

• Na X Ta = Nb X Tb

• Na / Ta = Nb / Tb

• Na + Ta = Nb + Tb

• Na - Ta = Nb - Tb

What is the formula to find Velocity Ratio for Inclined Plane?

• V.R. = H / D

• V.R. = D X H

• V.R. = D / H

• V.R. = D + H

What is the formula to find the Velocity Ratio for Wheel & Axle?

• V.R. = r / R

• V.R. = R + r

• V.R. = R / r

• V.R. = R X r
