What is point load test? Point Load (PL) is a test that aims at characterizing rock materials in terms of strength. Point Load test is an alternate method that can be used to adequately predict the uniaxial compressive strength of a rock material using a portable and simpler equipment. What is the purpose of the […]

What are the causes of equipment failure? 5 common causes of equipment failure Cause #1: Improper operation. Cause #2: Failure to perform preventive maintenance. Cause #3: Too much preventive maintenance. Cause #4: Failure to continuously monitor equipment. When to use condition-based monitoring. Cause #5: Bad (or no!) What are the causes of frequent failure of […]

Is it easy to install a starter? Replacing a starter will vary in difficulty between cars. Some cars, generally those with longitudinally mounted(front to back) engines, the starter is extremely easy. Lift the car, starters right there, unplug it, undo two bolts and you’re out. Reverse to install new one. Where do the wires go […]

Why is it important to clean each piece of metal with sandpaper? It is important to clean metals with sandpaper to remove oxides present on it . The oxides gets deposited on the metal due to action of air and dust. Why is it important to sand the metals before placing them in the metal […]

How do you create a bubble sort algorithm? Bubble sort Look at the first number in the list. Compare the current number with the next number. Is the next number smaller than the current number? Move to the next number along in the list and make this the current number. Repeat from step 2 until […]

Do struts affect camber? Bending a strut may bring camber back into range – assuming the wheel isn’t off more than one-and-a-half degrees (which is the maximum limit for bending any strut). Is camber adjusted during an alignment? An alignment essentially requires squaring a car’s wheels and axles with each other so that they’re moving […]

What can the IAEA do? The International Atomic Energy Agency (IAEA) serves as the world’s foremost intergovernmental forum for scientific and technical cooperation in the peaceful use of nuclear energy. The IAEA works with its 164 Member States and multiple partners worldwide to promote safe, secure and peaceful use of nuclear energy. Why are some […]

How do you calculate thermal expansion of a pipe? ΔL = aLo(T2-T1) (Equation 5) If the pipe is installed at an ambient temperature of 70 deg F, and the temperature of the pipe increases to 270 deg F, we can expect about 1.5 in of expansion in the 100 ft unanchored run. How do you […]

Where is the SDS log kept? SDSs must be stored in the work area (not far away or in another building). If electronic copies are used, SDSs must still be available if the area loses electricity or internet access. What does SDS stand for regarding hazard communication? provide Safety Data Sheets Where can you find […]

How many volts should a voltage regulator put out? 12 volts Is 14.8 volts too high for alternator? 14.8 would start to be a worry (there might be liquid or corrosion on the battery) and 15 volts would be a real concern, but 14.6 is fine. Less than 14.3 would be a “weak” alternator or […]
