Answer:
The inventor's claim is false in the sense that no thermal machine can violate the first thermodynamic law.
Explanation:
The inventor's claim could not be possible as no thermal machine can transfer more heat than the input work consumed. If we expose the thermal efficiency:
Where Q and W both must be in the same power unit, so we will convert the remove heat from BTU/hr to hp:
Therefore by comparing, we notice that the removing heat of 4.75 hp is large than the delivered work of 1.11 hp. By evaluating the efficiency:
[tex]n=4.75 hp / 1.1 hp = 4.3 > 1[/tex]
Answer:give the cart another shape
Explanation:an aeroplane shape makes it fast,,in physical science,the streamlined body makes a body fast
To solve this problem we will apply the concepts related to Soderberg's relation, which will allow us to find the safety factor based on yield stress, endurance strength, the mean and average stress. The mean and average stress values can be found through the alternating Stress previously given. We will proceed by defining the known values, that is
Yield stress 
Endurance strength 
The two values for alternating stress are


We know that mean stress is


And the average stress is


According to Soderberg relation




Therefore the factor of safety is 2
Answer:
Air is a gas
Explanation:
i think. beavuse it cant be a liqued or a solid. i dont think a plasma. i would answer gas
we can see that the correct person here will be Technician B who says that a diesel engine is designed to operate at near or maximum speed for long periods without damage.
<h3>What is a diesel engine?</h3>
A diesel engine is actually known to be an engine that makes use of diesel as its fuel. In other words, diesel engines run on diesel.
We see here that a diesel engine is actually designed to work for a very time on near or maximum speed without damage. This is true because the diesel fuel has that strength.
Also, diesel engines may be designed as two or four stroke cycles.
