How does a wedge make work easier?

A wedge is a simple machine that consists of two inclined planes giving it a thin end and thick end. … A wedge makes work easier by increasing the force applied to the object although it applies the force over a shorter distance. This gives the wedge a mechanical advantage greater than 1.

How wheel and axle make our work easier?

According to Mediahex a wheel and axle makes work easier by changing the amount of force applied to a load. The object that is being moved is a load located at the axle. A force applied at the outer edge of the wheel moves the load.

What makes work easier by increasing distance and decreasing force?

A machine is any device that makes work easier by changing a force. Machines may increase the strength of the force increase the distance over which the force is applied or change the direction in which the force is applied.

How does a simple inclined plane make work easier?

Inclined planes make it easier to move objects to a higher elevation. The sloping surface of the inclined plane supports part of the weight of the object as it moves up the slope. As a result it takes less force to move the object uphill.

How do you use a screwdriver safely?

Screwdriver safety

Do not use a screwdriver as a punch wedge pinch bar or pry.
Keep the tip clean and sharp to permit a solid grip on the tip of the screw.
Keep the handle of the screwdriver clean and intact to allow for a solid grip.
Never hold the piece you are working on in your hand.

Why the tip of a screwdriver is made flat and sharper?

Answer: The tip of an allpin made sharp so that that acts on a very small area so we have sufficient large pressure thereby allpin can easily penetrate when we give thrus.

Who invented screwdriver?

Henry Frank Phillips
Henry Frank Phillips (June 4 1889 – April 13 1958) was an American businessman from Portland Oregon. The Phillips-head (“crosshead”) screw and screwdriver are named after him.

Why tools are properly insulated?

Insulated hand tools provide two types of protection for workers around live electrical equipment. First they help protect individuals against electrical shock and arcing. Second they help protect the equipment being inspected or repaired.

Do machines make work easy?

A machine is any device that makes work easier by changing a force. A machine can do this by increasing the output force or by increasing the output distance and sometimes by changing the direction of the input force.

How does a second class lever make our work easier?

Answer: second class lever load is located between the effort and the fulcrum. if load is closer to the fulcrum than the effort then less effort will be required to move the load.

How do simple machines work?

A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses the work done on the load is equal to the work done by the applied force. The machine can increase the amount of the output force at the cost of a proportional decrease in the distance moved by the load.

Why are screws better than nails?

When deciding between nails and screws keep in mind that nails are less brittle so they provide greater shear strength. … Screws on the other hand may not be as forgiving but their threaded shafts hold better in wood and draw boards together much more tightly and they have greater tensile strength.
