Mechanical Advantage questions? | Yahoo Answers

Jun 02, 2012 · 1st question- A pulley is 92.5% efficient with a mechanical advantage of 10.0 You are using it to raise your boat out of the water at the harbor. If your boat has a mass of 1200 kg and you need to lift it a minimum of 1.5 meters to clear the pier, what input work will you need to do on the pulley? What amount of rope will you need to pull out to raise the boat to this height?

Simple Machines - Levers - Welcome to MATC

Question #1 - The effort force must be applied as far from fulcrum as the load is from the fulcrum. That is, symmetry rules, so the right side is a mirror image of the left side. Question #2 - The MA is 1. No advantage, no disadvantage. The mechanical advantage is the ratio of the load/effort ... 200/200 = 1

The Mechanical Advantages of Simple Machines - SAS

"The difference in the value of F between using a machine and not using one is the mechanical advantage of the machine. "All simple machines offer mechanical advantage, which is why we use them. With levers, the mechanical advantage comes from the ratio between the length of the lever on either side of the pivot.

Pulleys and Mechanical Advantage Systems | CMC PRO

Pulleys in Mechanical Advantage Systems. Pulleys perform two distinct functions in mechanical advantage systems. If the pulley is attached to the anchor, it is called a fixed or change of direction pulley. Its job is to change the direction of pull on the rope. If the pulley is attached to the load, it is a movable or mechanical advantage pulley.

Simple Machines --What is Mechanical Advantage

The actual mechanical advantage is the mechanical advantage of a real machine. Actual mechanical advantage takes into consideration real world factors such as energy lost in friction. In this way, it differs from the ideal mechanical advantage, which, is a sort of 'theoretical limit' to the efficiency.
