Las máquinas simples

Which of the following is NOT considered a simple machine?

• Lever

• Pulley

• Computer

• Inclined Plane

What is the main advantage of using a first-kind lever?

• It increases the speed of motion.

• It increases the distance of motion.

• It reduces the force needed to overcome resistance.

• It changes the direction of the applied force.

In a second-kind lever, where is the resistance located?

• At the fulcrum

• Between the power and the fulcrum

• At the end of the lever

• Between the fulcrum and the power

Which simple machine consists of a cylinder with a rope wound around it?

• Wedge

• Inclined Plane

• Lathe

• Pulley

How do pulleys make work more comfortable?

• By reducing the weight of the load

• By increasing the speed of lifting

• By increasing the distance of lifting

• By changing the direction of the applied force

What is the primary function of an inclined plane?

• To change the direction of force

• To increase the speed of motion

• To distribute effort over a greater distance

• To reduce the weight of the load

How does a screw transform motion?

• From linear to circular

• From circular to rotational

• From rotational to linear

• From linear to rotational
