The efficiency of a screw is typically lower compared to other machines because a significant amount of input energy is lost to friction between the screw threads and the surface it is turning against. Additionally, there may be energy losses due to heat generation.

How the efficiency of the screw jack is increased?
The efficiency of a screw jack can be increased by reducing friction between the screw and the nut through proper lubrication, using a finer pitch screw for smoother operation, and ensuring that the screw and nut are properly aligned to minimize binding. Additionally, using a larger diameter screw can help distribute the load over a larger area, reducing wear and improving efficiency.
Why a high-efficiency machine is more desirable than a low- efficiency machine?
High-efficiency machines do more for less and are therefore more desirable than a low-efficiency machine.AnswerHigher efficiency means lower energy losses and, therefore, such machines are more economical than low-efficiency machines.
How can you increase the IMA of a screw?
To increase the IMA (Index of Machine Ability) of a screw, you can increase the thread pitch or decrease the head diameter. Both of these adjustments will increase the mechanical advantage of the screw, making it easier to drive and increasing its efficiency.
What are the sources of error in case of screw jack?
Some potential sources of error in a screw jack include friction in the threads, misalignment of the components, deformation of the screw or load, and inaccurate torque measurement. These errors can affect the efficiency and precision of the screw jack's lifting capabilities. Regular maintenance and calibration can help reduce these errors.
What is the rate of heat output of a Carnot engine?
The rate of heat output of a Carnot engine depends on the temperature of the hot reservoir and the temperature of the cold reservoir. It can be calculated using the Carnot efficiency formula, which is the temperature difference between the hot and cold reservoir divided by the temperature of the hot reservoir.

What do you mean by self locking screw Derive an expression For efficiency of screw?
this screw is locked it self without any external forces
Why low efficiency bulbs are called energy savers?
They are not. Low E bulbs are low ENERGY, not low efficiency. They are actually highly efficient.
Why is a high efficiency machine is more desirable than a low efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).

What is the efficiency of screw jack?
Type your answer here... (1+sin$)/(1-sin$)
Is the solar panels high low medium in efficiency?
Low
Is it always a good idea to discard low efficiency?
No...... Not always........... They can be modified to high efficiency..............
The efficiency of the wedge is low because of?
friction or The mechanical advantage is greater for thinner wedges. However, the efficiency is low because of the large amount of friction.
330 homelite chainsaw which screw is the high and which is the low the longer screw is what?
The longer screw is for the idle speed. On the carburetor you will find little letters cast next to each needle adjusting screw. H is for High, and L is for low. http://store.chainsawr.com/
What is braking efficiency in railway braking?
pretty low
Is low efficiency the same asmost energy efficient?
No.
