Calculation should include
- the positive and negative effects of resistance for each energy system
- the formula for measuring resistance in each system, including
- mechanical—Fstatic=μsN and Fkinetic=μkN
- mechanical—RD=F /v
- fluid—Rfluid=-ΔP/V
- electrical—R=ΔV/I
- thermal—Rthermal=-ΔT/QH.
Process/Skill Questions:
