Biomechanics

Biomechanics deals with which of the following?

• force
• matter
• motion
• all of these

The purpose of a machine (simple or otherwise) is to 

• multiply a resistance
• move the fulcrum
• multiply a force you apply
• lengthen the effort arm

Which MA formula is correct? 

• Effort / Resistance
• Resistance / weight
• Length of resistance arm / length of effort arm
• Length of effort arm / length of resistance arm

In the body, the effort is the 

• muscle insertion
• muscle origin
• bone
• joint

In the body, the fulcrum is at a 

• muscle
• joint
• insertion
• weight

Which order would be correct for a first class lever?

• FRE
• REF
• EFR
• FER

Which part of a lever is in the middle in a second class lever?

• Fulcrum
• Resistance
• Effort
• Effort arm

MA is the number of times the ____ 

• resistance is multiplied
• effort is multiplied
• resistance is divided
• effort is divided

When MA is low (below 1), what is gained by using a lever if it is harder to use?

• more effort
• less effort
• more ROM
• less ROM

In the body, a wheel and axle can do all of the following EXCEPT

• increase resistance
• increase ROM
• increase speed
• increase distance
