because there is more input then output... in other words, friction. (:
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.
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.
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.
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.
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.

this screw is locked it self without any external forces
They are not. Low E bulbs are low ENERGY, not low efficiency. They are actually highly efficient.
On a STIHL chainsaw carburetor, the "high" screw (often marked as H) adjusts the fuel mixture for high-speed operation, affecting performance at full throttle. The "low" screw (marked as L) controls the fuel mixture for low-speed operation, impacting idling and initial acceleration. Proper adjustment of these screws is crucial for optimal engine performance and efficiency. Always refer to the specific model's manual for precise tuning instructions.
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).
The type of chiller that uses a screw type impeller is typically known as a screw chiller. These chillers employ a twin-screw compressor, which compresses refrigerant using two rotating screws. They are known for their efficiency, reliability, and ability to handle large cooling loads, making them ideal for industrial applications and large commercial buildings. Screw chillers are also recognized for their low maintenance requirements and operational versatility.
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/

Type your answer here... (1+sin$)/(1-sin$)
Low
No...... Not always........... They can be modified to high efficiency..............
friction or The mechanical advantage is greater for thinner wedges. However, the efficiency is low because of the large amount of friction.
