Mechanical advantage Study guides, Study notes & Summaries

1. An induction clutch works by: magnetism 2. If a first class lever with a resistance arm measuring 2 feet and an effort arm measuring 8 feet are being used, what's the mechanical advantage?: Length of Effort Arm ÷ Length of Resistance Arm. MA = 8 ÷ 2 = 4 3. The force produced when a boxer's hand hits a heavy bag and "bounces" off it is called: recoil 4. If Gear 1 has 25 teeth and Gear 2 has 15 teeth, how many revolutions does Gear 2 make for every 10 revolutions Gear 1 makes?: r = DR/...

ARDMS SPI STUDY GUIDE QUESTIONS AND ANSWERS ALREADY PASSED In soft tissue, if the frequency of a wave is increased the Propagation Speed (PS) will... Remain the Same because stiffness and density affect Propagation Speed. What is the audible range? 20-20,000Hz >20,000Hz=Ultrasound Frequency is measured in Hertz (Hz) is Cycles per Second Not affected by sonographer Increase Frequency; Decrease Depth A period is the length of time it takes for one complete wavelength to pass a fixed poin...
