What is it called when Force applied to a simple machine?
When a force is applied to a simple machine, it is called input force. This force is used to overcome resistance or mechanical advantage within the machine to perform work. The input force is typically different from the output force, which is the force the machine exerts to accomplish a task.
You test a machine and find that it exerts a force of 5 N for each 1 N of force you exert operating the machine What is the actual mechanical advantage of the machine?
The mechanical advantage is 5. This means that for every 1 N of force you exert, the machine will output 5 N of force.
What is the force a 800N man exerts on the earth?
The force that an 800N man exerts on the Earth is equal in magnitude but opposite in direction to the force that the Earth exerts on the man, by Newton's third law. So, the force the man exerts on the Earth is 800N.
What does a machine exert?
A machine exerts force or power to perform a specific task or function, such as moving objects, lifting weights, or generating electricity. The type and amount of exertion depend on the design and purpose of the machine.
Three examples of force pairs that happen when homework is being done?
The hand exerts a force on the pen to write on paper, while the pen exerts an equal but opposite force back on the hand. The book exerts a force on the table due to gravity, while the table exerts an equal but opposite force upwards on the book. The foot exerts a force on the ground to stay balanced while sitting on a chair, and the ground exerts an equal but opposite force upwards on the foot.
