Answer 28

Motion swinging from side to side

Question 29

What is an example of a product that only uses oscillating motion?

Answer 29

A pendulum in a clock

Question 30

Explain a first order lever

Answer 30

Fulcrum is between the effort and the load if the fulcrum is moved closer to the load then less effort is required to move the load, although the load does not move as far.

Question 31

Explain a second order lever

Answer 31

The load and effort are on the same side of the fulcrum. The load is nearer the fulcrum so less effort is required to move the load

Question 32

Explain a third order lever

Answer 32

Has the load and the effort on the same side as the fulcrum. the load is far from the fulcrum

Question 33

Explain a simple linkage and a product that uses it

Answer 33

Direction of motion is reversed but magnitude of forces are equal as the distances from the pivot are equal. These are often used on clothing horses

Question 34

Explain a bell crank linkage and a product it’s used in

Answer 34

In a bell crank linkage the direction of motion is turned through 90 degrees but the magnitude of the output force is greater than the input force. Amount of output force can be changed by moving fixed pivot used in bicycle brakes

Question 35

Explain a parallel motion linkage and a product it’s used in

Answer 35

Often referred to as push pull linkage the direction of forces and the magnitude of forces are the same but are used when the force cannot be transferred directly in a straight line often used in the expanding tool boxes
