SIMPLE MACHINES-INCLINED PLANE, WEDGE, SCREW WITH VERIFIED SOLUTIONS

How can an inclined plane make work easier? By reducing the amount of force it takes to raise an object. What is the tradeoff when you use an inclined plane to make work easier? The force must be applied over a greater distance (you have to push it farther). What is another name for an inclined plane? a ramp Which takes more force? Lifting a brick straight up to the top of a stack of books? or Pushing it along an inclined plane from the starting point to the top of the stack of books? Lifting a brick straight up Which requires you to move the load farther? Lifting a brick straight up to the top of a stack of books? or Pushing it along an inclined plane from the starting point to the top of the stack of books? Pushing it along an inclined plane from the starting point to the top of the stack of books? How is a wedge like an inclined plane? Both have at least one slanted side. In fact, a wedge is basically 2 inclined planes that are back-to-back. How is a wedge different from an inclined plane? To move an object using an inclined plane, you apply the force directly to the object. However, to move (split or separate) something using a wedge, you apply the force to the wedge and it translates the force to the object. What is a wedge used for? Cutting, splitting, piercing and separating How does a wedge make it easier to lift a load? It reduces the amount of force needed to lift the load. What is the tradeoff when using a wedge to lift a load? In order to use less force to lift or separate an object, you need to move the wedge a greater distance. When you push a wedge down into something, which way do the separated parts move? The downward force of the wedge it transferred to push the separated objects outward or to each side. The screw is related to what other simple machine? inclined plane How is a nail similar to a screw? Both have a wedge at the tip to split apart the wood. How is a nail different from a screw? The nail moves in the same direction as the force applied to it by the hammer. However, the screw requires a twisting force (torque). Depending upon which way you twist, the screw will go up or down. Which is easier to drive into the wood? nail or screw? Screw Which takes longer to drive into the wood? nail or screw? Screw How do screws make your work easier? They reduce the amount of force needed to drive the fastener (screw) into the wood. What is the tradeoff when using a screw? It takes longer to drive the screw into the wood than it does to pound in a nail.
