Answer:
c) Young's modulus Toughness.
Explanation:
The charpy impact test is well known in the Engineering field specifically in stress, strain and mechanical of fracture.
A theoretical definition is that the test determines the amount of energy absorbed by a material during fracture.
Answer:
Resulting heat generation, Q = 77.638 kcal/h
Given:
Initial heat generation of the sphere,
Maximum temperature,
Radius of the sphere, r = 0.1 m
Ambient air temperature, = 298 K
Solution:
Now, maximum heat generation, is given by:
(1)
where
K = Thermal conductivity of water at
Now, using eqn (1):
max. heat generation at maintained max. temperature of 360 K is 24924
For excess heat generation, Q:
where
Now, 1 kcal/h = 1.163 W
Therefore,
Technician A is correct. Technician B is wrong because a gear's transmission is used to increase or decrease torque.
The relation torque is relying on multiplying the circumferential detail with the resource of the usage of the radius; massive gears experience a greater amount of torque, at the same time as smaller gears experience a great deal much less torque. Similarly, the torque ratio is equal to the ratio of the gears' radii. A gear's transmission torque modifications as it will boom or decreases speed. Commonly, with the resource of the usage of lowering the speed, a small torque on the doorway issue is transferred as a massive torque at the output issue. The calculation of torque is quantified with the resource of the usage of an extensive form of teeth.

We can assume that the job Timothy is working on is in the older building. Thus, the correct option is A.
<h3>What is an ungrounded receptacle?</h3>
An ungrounded receptacle may be defined as the ground wire required to deliver the same level of protection from house fires and electrical shocks suggested by grounded doorways.
The ungrounded receptacles are only furnished in the building that is already built up to a certain level with appropriate dimensions. It connects all the electrical appliances of the home through a cage of metallic or copper wire.
Therefore, the correct option is A.
