What describes the relationship between friction and IMA for a simple machine?
Friction reduces the mechanical advantage (IMA) of a simple machine by causing energy losses in the form of heat. As friction increases, the effectiveness of the machine in transmitting force or lift decreases, ultimately lowering the mechanical advantage.
What is the relationship between friction and efficiency of a machine?
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
What machines use to lower friction between moving parts?
Ideal Machine
What do machines use to lower friction between moving parts?
Ideal Machine
Does a well oiled machine has friction?
Yes, a well-oiled machine can still have some friction, but the oil helps to reduce it. Friction occurs when there is resistance between moving parts, and the oil acts as a lubricant to minimize this resistance. Regular maintenance and lubrication are essential to keep friction to a minimum in a well-oiled machine.
What do some machine use to lower friction between moving part?
Machines use lubricants such as oil or grease to lower friction between moving parts. These substances create a thin film between the surfaces, reducing direct contact and minimizing friction and wear. Additionally, materials with low friction coefficients, like certain polymers or coatings, can also be used to reduce friction.
What is one way to overcome friction in a machine?
use lubricants it smoothens the surface and reduces the irregularity between both the surfaces resulting in reduction of friction
Are the friction losses of an induction machine linear?
No, the friction losses of an induction machine are not linear. These losses are typically influenced by factors such as speed, load, and temperature, which can make the relationship between friction losses and operating conditions non-linear.
How do you increased machine efficiency?
By reducin friction between the machine parts and also by avoiding any sorts of power losses.
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 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 can make machines more efficient by reducing friction?
the relationship between them is that the machines have friction that makes the machine goes
