A block-and-tackle system increases the input force by distributing it across multiple pulleys. As the force is applied to the rope, it is redirected and distributed through the pulley system, allowing the load to be lifted with reduced effort. This mechanical advantage is achieved by increasing the length of rope that needs to be pulled, thereby decreasing the amount of force needed to lift the load.

What is a device that can multiply and change the direction of an input force?
A simple machine like a pulley can multiply and change the direction of an input force. By using multiple pulleys in a system, you can create a mechanical advantage that amplifies the force applied.
Is mechanical advantage output force divided by input force?
Yes, mechanical advantage is calculated by dividing the output force by the input force. It provides a measure of how much a machine can multiply force or distance.
Can a machine multiple input force Input distance Input energy?
Yes, a machine can multiply input force by input distance to increase input energy. This concept is known as mechanical advantage, where the machine amplifies the input force to output more energy than what was initially supplied.
How do you calculate the work input of a lever?
To calculate the work input of a lever, you can use the formula: work input = effort force x effort distance. The effort force is the force applied to the lever, and the effort distance is the distance the effort force acts over. Multiply these values to find the work input.
Does the wedge multiply force?
No, the wedge does not multiply force. It allows a smaller force to exert a greater force over a larger distance by converting the input force into two separate forces that act perpendicular to each other.
Does a fixed pulley multiply input force?
no it can't.

How do you find the output force of a 1st class lever?
Multiply (the input force) x (the lever's mechanical advantage).
How do you calculate the work input of a lever?
To calculate the work input of a lever, you can use the formula: work input = effort force x effort distance. The effort force is the force applied to the lever, and the effort distance is the distance the effort force acts over. Multiply these values to find the work input.
Does a moveable pulley multiply the input force?
Yes. The IMA of a movable pulley is 2.
Does the wedge multiply force?
No, the wedge does not multiply force. It allows a smaller force to exert a greater force over a larger distance by converting the input force into two separate forces that act perpendicular to each other.
How do you find the output force of a wheel and axle if you already know the input force?
To find the output force of a wheel and axle, you can use the formula: Output Force = Input Force * (Radius of Wheel / Radius of Axle). The output force is determined by the ratio of the radii of the wheel and axle, with the input force determining the overall scaling factor.
What does a machine not do multiply force multiply energy change direction of a force or work?
Does not multiply energy. Work done or energy used (force * distance) remains the same at both ends. Force or torque can be increased or decreased depending on mechanical advantage. It can change the direction of the force or torque.
Which class of lever does not multiply input force?
A class 1 lever does not multiply input force. In this type of lever, the fulcrum is positioned between the effort force and the load, resulting in no mechanical advantage gained. An example of a class 1 lever is a see-saw.
How do machine multiply force?
Machines can multiply force through mechanisms such as levers, gears, or pulleys. These devices allow for the transfer and amplification of force to increase the output. By manipulating the arrangement and size of these components, machines can effectively multiply the input force to perform tasks that would be challenging with human effort alone.
