The voltage of a battery powering a series circuit would need to be the sum of voltages required by each light bulb and any other elements in the circuit. Based on where the applied effort and resistance are located, identify the force required to hold the system in equilibrium. The following is a printout of the Statistics command for Inventory Value at Cost: Field : Value. Illustrations should consist of basic simple machine functional sketches rather than realistic pictorials. Use your fingers to turn the wheel.

These simple machines fall into two classes: i the inclined plane, wedge, screw characterized by the vector resolution of forces and movement along a line, and ii the lever, pulley, wheel and axle characterized by the equilibrium of torques and movement around a pivot. Use your fingers to turn the axle. Use Chapter 4 Powerpoint question 4. Simple Machines — Lever A first class lever in static equilibrium has a 50lb resistance force and 15lb effort force. What is the actual mechanical advantage of the system? Examples: Screw, Wheel and Axle, Wedge, Pulley, Inclined Plane, Lever Compound Machine: Two or more simple machines working together to make work easier. The length from the wheel and axle to the effort is 5 ft. This is determined by reading the number at the bottom of the screen.

The 2nd class of levers are objects that have the fulcrum on the opposite side of the applied force like a nutcracker. The 3rd and final class is objects like crab claws. Slope is equal to the rise of the ramp divided by the run of the ramp. Each question requires proper illustration and annotation, including labeling of forces, distances, direction, and unknown values. What is the required wheel diameter to overcome the resistance force? Simple Machines — Pulley System A construction crew lifts approximately 560 lb of material several times during a day from a flatbed truck to a 32 ft rooftop. The report on the following page shows gross pay by department.
