How does friction affect output force?
Simply put, friction reduces output force. The more friction there is, the less effectively power will be delivered, and this results in reduced output force.
How does lubricating a machine affect the output work from that machine?
Lubricating a machine reduces friction between its moving parts, allowing them to move more freely and smoothly. This can result in improved efficiency and reduced wear and tear on the machine, ultimately leading to increased output work by maintaining optimal functioning of the machine.
What happens to the mechanical advantage of a machine if friction is reduced through the use of oil or some other means?
Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.
What is the difference between a ideal machine and real machine?
In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .
How lubericating a machine affects the output force exerted by the machine?
It maximizes it, by reducing the internal losses to friction.
How does the friction between the parts of a machine affect the work input and work output?
Friction between the parts of a machine decreases the work output by converting some of the input energy into heat. This results in inefficiencies and reduces the overall performance of the machine. To compensate for the energy loss due to friction, more work input is required to achieve the desired work output.
What increases the work output of a simple machine?
Increasing the input force or the distance over which the force is applied can increase the work output of a simple machine. Reducing friction within the machine can also help to increase its efficiency and work output.
How does friction change a machines mechanical advantage?
Friction reduces the efficiency of a machine by converting some mechanical energy into heat. This means that the output force of a machine can be lower than expected due to frictional losses, which can reduce its mechanical advantage. In other words, friction can make it more difficult for a machine to perform work by increasing the force needed to overcome resistance.
The output work of a machine compared to the input work is?
The output work of a machine is typically less than the input work, due to factors such as friction, heat loss, and other inefficiencies in the machine's operation. This difference between input and output work is known as the efficiency of the machine.
Besides a reduction in friction the only way to increase the amount of work output of a machine is to the work input.?
Increasing the work input to a machine is a way to enhance its work output beyond minimizing friction. By supplying more energy to the machine, it can perform more work. This principle follows the law of conservation of energy, where the work input equals the work output plus any energy losses due to factors like friction.
The amount of work done on a machine is 300 j and the machine does 50 j of work. what can you say about the amount of friction that the machine has while operating?
The machine has 250 J of work due to friction because the work done on the machine (300 J) is greater than the work output by the machine (50 J). This indicates that friction is opposing the motion of the machine and causing energy loss.
Why is the work output of a machine never to the work input?
Some work input is used to overcome friction.
