EX 1: A first class lever, in revolution equilibrium, has a 50 lb resistance forces and also 15 lb effort force. The lever\"s effort force is located 4 ft native the fulcrum.1. Sketch and annotate lever system explained above

2. Calculate:Actual Mechanical benefit (AMA)AMA= pressure Resistance/Force EffortAMA= 50 lbs/15 lbsAMA= 3.333. Static Equilibrium Calculations:DR= street of Resistance ForceM= moment (Force x distance)Moment initiative + minute Resistance-->
EX 2: A wheel barrow is supplied to lift a 200 lb load. The length from the wheel axle come the center of the load is 2 ft. The size from the wheel and axle to the effort is 5 ft.1. Illustrate and also annotate lever system explained above

Ideal Mechanical benefit (IMA)IMA= Distance(effort force)/Distance(resistant force)IMA= 5 feet/ 2 feetIMA= 2.53. Static Equilibrium Calculations: FE= pressure of effort Force M= moment (Force x distance)Moment effort + minute Resistance
A clinical technician offers a pair that 4 inch long tweezers to eliminate a wood sliver from a patient. The technician is applying 1 lb of squeezing pressure to the tweezers. If much more than 1/5 lb of force is applied to the sliver, it will certainly break and also become difficult to remove.

2. Calculate:Actual Mechanical advantage (AMA)AMA= force Resistance/Force EffortAMA= 1 lb/ (1/5) lbAMA= 0.23. Static Equilibrium Calculations: DR= street of effort ForceM= moment (Force x distance)Moment effort + moment Resistance
A building crew lifts about 560 lb of product several times during a job from a flatbed van to a 32 ft rooftop. A block and tackle device with 50 lb of initiative force is designed to lift the materials.

I'm still confused on how specifically you gained 9 strands, where did you regulate to acquire 4 moveable pulleys?
