I need to lift 75 pounds when only using 4 pounds of force. Is there a gear set or pulley system that can do that?
Thanks

Power transmission is the process of transferring mechanical energy from one location to another. This can be done through various mechanisms, such as gears and pulleys, which allow for the movement and transfer of energy from a power source to a desired output.
Gears are mechanical devices with teeth that interlock and rotate to transmit power and motion. When two gears of different sizes are connected, the smaller gear (pinion) will rotate faster, while the larger gear (gear) will rotate slower. This difference in rotational speed allows for the transfer of power from one gear to another.
There are various types of gears used in power transmission, including spur gears, helical gears, bevel gears, and worm gears. Each type has different properties and is used for specific applications depending on factors such as speed, torque, and direction of rotation.
A pulley is a simple machine that is used to change the direction of a force or to transmit power. In power transmission, pulleys are often used to transfer power from one shaft to another by wrapping a belt or rope around the pulley and connecting it to the desired output shaft.
Gears and pulleys offer several advantages in power transmission, including efficient transfer of power, speed reduction or increase, and the ability to change the direction of motion. They also have a compact design, low maintenance requirements, and can handle high loads and torque, making them suitable for a wide range of applications.
