Let’s Recall (Review) Direction: Enumerate 5 OHS policies in installing network cable 1. 2. 3. 4. 5. are Many exclusive techniques are used for cable set up.

<h3>Why is OSH applicable to commercial enterprise?</h3>

Research has proven that protection and wellbeing on the place of job equal exact commercial enterprise and profitability. Employers have number one duty for the occupational protection and fitness of workers.

Many exclusive techniques are used for cable setup. These consist of pulling, blowing and pushing into ducts, direct burial and aerial set up. The maximum essential homes of cables at some stage in set up are the tensile force, the bending radius and the set up temperature.

Comte identified three basic methods for discovering these invariant laws, observation, experimentation, and comparison.

Match the test to the property it measures.

Vinvika [58]

Answer:

a. Rockwell 3. hardness

b. Instron 2. stress vs strain

c. Charpy 1. impact strength

d. Fatigue 4. Endurance Limit

e. Brinell 3. hardness

f. Izod 1. impact strength

Explanation:

Izod and Charpy are the impact strength testing procedure of a material in which a heavy hammer is attached to an arm is released to impact on the test specimen. In Izod test the specimen with v-notch is held vertical with the notch facing outward while in Charpy test the specimen is supported horizontally with notch facing inward to the impacting hammer.

Instron testing system does universal testing of the material which gradually applies the load recording all the stresses and the corresponding strains until the material fails.

Fatigue is the property of a material due to which it fails under the repeated cyclic loading by the initiation and propagation of cracks. The property of a material resist failure subjected to infinite number of repeated cyclic loads below a certain stress limit.

Rockwell and Brinell are the hardness testing methods. In Rockwell test an intender ball is firstly pressed against the specimen using minor load for a certain time and then a major load is pressed against it for a certain time. After the intender is removed the depth of impression on the surface is measured while in case of Brinell hardness we apply only one load against the intender ball for a certain time and after its removal the radius of impression is measured.

A large heat pump should upgrade 5 MW of heat at 85°C to be delivered as heat at 150°C. Suppose the actual heat pump has a COP o

AysviL [449]

Answer:

W=2 MW

Explanation:

Given that

COP= 2.5

Heat extracted from 85°C

Qa= 5 MW

Lets heat supplied at 150°C = Qr
