A delivery person has several boxes stacked on a hand truck. Would it take more force to push the hand truck when it is more horizontal or more vertical? Why? | Horizontal. The force arm remains constant, while changing the angle of the hand truck lengthens/shortens the resistence arm. Lowering load (horizontal)= more force. Raising load (more vertical)=less force (shorter resistence arm/less force). |

In terms of BOS, why is it more difficult for a person in a wheelchair to balance on only the back wheels ("wheelie's") rather than on all 4 wheels? | The BOS of a wheelchair during a "wheelie" is very narrow. To maintain balance the person must keep the body's COG w/in that BOS. The BOS is very wide when the wheelchair is resting on all 4 wheels & it's easy to keep the body's COG within it. |

Prior to moving the patient, what can the people do to increase their own stability? | People need to get as close to the bed as possible as it shortens their lever arms; they need to move their legs apart~Esp in the A/P direction as it increases their BOS; they need to bend their knees slightly as it lowers their COG. |
When cracking an almond with a nutcracker, will the almond be easier to crack if it is closer to the axis or closer to the end of the handles? Why? | Closer to the axis makes the resistance arm shorter = easier to crack. |
Give an example of bony structures at the knee acting as a pulley to increase the angle of pull: | The med. condyles of the tibia & femur increase the angle of pull of the gracilis. The patella & femoral condyles increase the angle of pull for the quadriceps. |
Explain why a person leans to the right when carrying a heavy suitcase in the left hand? If the suitcase was very heavy, what might the person do with their right arm? Why? | COG has shifted to left when carrying on left. By leaning to right, the COG is brought back over the BOS. A very heavy suitcase will further shift the COG, so besides leaning to right, they might also raise the right arm out to the side. |
Why are rubber tips put on the ends of crutches? | To increase the amount of friction between the crutch tip & the ground to prevent slippage. |
