The Lever is being used to pick up diamonds using tweezers
A complex machine is a machine using more than one simple machine for its operation. A bicycle is a complex machine, using a lever for steering (handlebars), wheel and axle, inclined plane (the threads on bolts), and a pulley (chain on sprockets).
the effort is decreased
Yes, it is it allows you to slide something off the pan without using a lot of effort its an incline plane
Efficiency means to calculate that is the machine is efficient enough to save your bill or use less electricity. To calculate the formula is:Efficiency = Energy output (what is the machine producing) divided by Energy input (what is the machine taking or using).
a washing machine means that wash the clothes . simple machine that makes work easyIf you are using a combo washer, there is the dryer. You will be amazed of the numerous features of washers today. You might be able to find a sensor in it as well. These sensors work in detecting sud or moisture content in your laundry. This helps a lot in conserving energy and water.Wheels and belts.wheel & axle, lever
I used tweezers to remove a splinter from my thumb.

A lever

When faced with not having tweezers, I improvised by using a pair of small pliers as makeshift tweezers.
The Mechanical Advantage is the ratio of the force needed to lift an object using the simple machine divided by the weight of the object
You are using a wheel and axle simple machine when you twist a doorknob. The wheel (the doorknob) rotates on the axle (the spindle), allowing you to easily open or close the door.
my results are that simple machines work by using force and some work.
A complex machine is a machine using more than one simple machine for its operation. A bicycle is a complex machine, using a lever for steering (handlebars), wheel and axle, inclined plane (the threads on bolts), and a pulley (chain on sprockets).
the work a machine does is the work output what it takes to do the work is the work input
A compound machine combines two or more simple machines to perform work more efficiently than a single simple machine. By leveraging the advantages of different simple machines working together, a compound machine can multiply the input force or distance, making it easier to accomplish tasks that would be challenging using just one simple machine.
