## Activity 1.1.2 Simple Machines Practice Problems Answer Key Essay Some simple machines are modified inclined planes. Be sure to document all solution steps and proper units. Slope is equal to the rise of the ramp divided by the run of the ramp. What is the ideal mechanical advantage of the system? Illustrate and annotate the lever system described above. Examples: Wheelbarrow, Can Opener, Bicycle Inclined plane: A sloping surface, such as a ramp. The screw is an inclined plane and is being slid up the entire way. Identify and defend what two simple machines you believe are combined to create a screw.

## 1.1.2.A. Simple Machines Practice Problems What is the mechanical advantage of the system? All problem calculations should assume ideal conditions and no friction loss. Pulling down on the rope can lift an object attached to the rope. Anyway what is input and output force? There are no exceptions in the calculation of net pay for September. For the combination circuit, explain the relationship between the current output at the battery and the current through each bulb in the parallel circuit. Using static equilibrium calculations, calculate the length from the fulcrum to the resistance force.

## Activity 1.1.2 Explain the primary difference between a series and a parallel circuit. 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. The 3rd and final class is objects like crab claws. All problem calculations should assume ideal conditions and no friction loss. Ramps make a trade off between distance and force. The length from the wheel axle to the center of the load is 2 ft.

## Activity 1.1.2 The motor being used to wind the cable in the pulley system can provide 100 lb of force. Use your fingers to turn the axle. For the combination circuit, explain the relationship between the voltage output at the interface and the voltage across the two light bulbs. Th e length from the w heel ax le to the center of the load is 2 ft. Be sure to document all solution steps and proper units. Friction- The force that resist motion between two surfaces that are touching each other.

## A1_1_2SimpleMachinesPracticeProblemsAnsKey (1) Examples: Staircase, Ramp Lever: A straight rod or board that pivots on a point known as a fulcrum. Determine the pitch of the screw. Sketch and annotate the wheel and axle system described above. The valve will encounter 200 lb of resistance force applied to a 1. Use the force sensor attached to the string wrapped around the wheel to create equilibrium. The 1st class levers are objects like pliers where the fulcrum is at the center of the lever. Based on where the applied effort and resistance are located, identify the force required to hold the system in equilibrium.

## Activity 1.1.2 Simple Machines Practice Problems Answer Key Essay Each question requires proper illustration and annotation including labeling of forces, distances, direction, and unknown values. What is the actual mechanical advantage of the system? A lever consists of a fulcrum, load, and effort force. Sketch and annotate the lever system described above. The valve will encounter 200 lb of resistance force applied to a 1. A block and tackle system with 50 lb of effort force is designed to lift the materials. The motor being used to wind the cable in the pulley system can provide 100 lb of force.

## Activity 2 Simple Machines Practice Problems Answer Key There are several types of simple machines. You use many machines in a day that you might take for granted. Wedges are used to split things. The technician is applying 1 lb of squeezing force to the tweezers. A winding road on a mountain side is a good example of a ramp. Please write down your fitted regression model. The valve will encounter 200 lb of resistance force applied to a 1.

## Activity 1.1.2 Simple Machines Practice Problems Answer Key Essay 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. A wheel barrow is used to li ft a 200 lb load. Based on where the applied effort and resistance are located, identify the distance traveled by both forces during one full rotation. The length from the wheel and axle to the effort is 5 ft. Almost every thing we do has a machine involved. What is the required actual mechanical advantage? There are no duplicate check numbers. What is the maximum weight of the lathe? The audit concern is that there may be unrecorded payroll transactions.
