What are the 3 types of lever?
THREE CLASSES OF LEVER There are three classes of lever and each class has fulcrum, load and effort which together can move a heavy weight. CLASS 1 The workman uses a trolley to move the large packing case. The fulcrum is the wheel. CLASS 2The gardener uses a wheel barrow to lift tools and garden waste. The load is in the centre of the barrow CLASS 3 The fisherman catches the fish which becomes the load at the end of the lever.
What is a second class lever?
A Class 2 lever has the load in-between the effort and the fulcrum. An example is a wheelbarrow, Effort is at the handles, the wheel is the fulcrum, and load is the weight carried on the wheelbarrow.
What are the advantages and disadvantages to each class of lever?
The last top answer just did not answer the question being asked, I understand that you want specifics when it comes to each class and the last guy just didn't understand that, but from my readings it seems that a class 3 has a mechanical disadvantage meaning it takes a stronger force to lift a smaller amount of resistance. What third class levers lack in lifting power it makes up with high velocity situations such as throwing something. meaning it is good with speed. Sorry but I have yet to figure out the other 2 classes
When Cam A completes one revolution the lever will touch the contact point how many times?

How many pounds of effort force does a lever have if it has an effort arm of fifteen units long and a resistance arm of 10 units and can lift a 3-pound weight?
It would require (3 X 10)/15 = 2 lb to lift the 3 lb weight. Actually, something a little greater than that. 2 lb is the force to balance it. (Obviously, the lever "has" no force. It requires the force to lift the weight.)
