You will see if changing the angle (by changing the height) of the inclined plane or adding mass to the resistance will change any of these. Remember to record all data and answer all questions on the lab write-up. ... (along the ramp angle), pull the cart up the ramp at a constant speed with the spring scale. Record the effort force needed.

A line that changes directions like this means an object is changing speed or direction as it moves. Object B begins by moving 25 meters at a constant speed for 6 seconds. (The red line's slope is less steep than the green line's, so Object B is moving more slowly than Object A.) Between 6 seconds and 14 seconds the line is horizontal.

Note: Pulleys were imported in various sizes from about 7.0 mm to 9.0 mm. Adjustments in speed can be made by changing pulleys. The larger the pulley, the faster the car, all other things being the same! STEP 10. Once the sealer has cured, reattach the spring belts, paint the flywheel and pulley flat black.

Activity 2.2.1 Observing Mechanisms
Changing pulleys changes the speed of the drill bit. When you are riding a multi-speed bicycle up a steep hill, what do you do? Most likely you shift gears in order to get more power with the same amount of effort. Sometimes when a standard shift or four-wheel drive vehicle is being driven up a steep incline, the driver will downshift or engage ...

T / F 5) Simple machines give us an advantage by changing the amount, speed or direction of forces. T / F 6) Simple machines require a much greater force to overcome a smaller force. T / F 7) The amount of effort saved when using a simple machine is called the simplification equilibrification equation.

There are different types of pulleys. Pulleys are. either fixed or movable. You attach a fixed pulley to one place. The fixed. pulley helps make work easier by changing the. direction of the effort. You hook a movable pulley to the object you are. lifting. As you pull, the object and the pulley. move together. This pulley does not change the

Belt driven fans and blowers can be set by adjusting the drive belt, and changing pulleys if necessary. Direct drive fans must be set by throttling the inlet or outlet, or by setting the speed with a manual speed controller. Throttling wastes energy and could cause instability, so the designer should specify manual speed controllers for all ...
