one or more can be correct please select from below options
Lower operating temperatures are more desirable as they reduce the viscosity making it easier to fill the cavity
This process can be used for both thermosets and thermoplastics as they can both be thermally shaped
This process can only be used for thermosets as they can thermally cure from the monomer state
This process is suitable for rubber, PVC and polymethyl methacrylate
How is it possible to decrease contact resistance?
O By using different fluids for better matching
O Using softer metal foils
Increasing surface roughness
O None of the above
O Using higher pressure when combining
Which one of these may increase the amount of contact resistance?
Lower temperature during matching of materials
decreasing pressure for pressing the materials together
Higher surface roughness
All of the above
Using air as a fluid for the gap instead of liquids

- Which of the following statements is not true about thermal cleaning? The main advantage of thermal cleaning is a total reduction of all oils and grease on and in blocks, heads, and other parts. After a part has been thermally cleaned, it should be submerged in water to cool it quickly. Thermal cleaning leaves behind a dry, powdery ash on the parts. After a part has been thermally cleaned, it should be washed or blasted with shotarrow_forwardWhat cautions must be taken when chemically cleaning oil or paint from a piece of metal?arrow_forwardWhat properties should a good leak-detecting solution have?arrow_forward

The gloves offer protection against cuts. The gloves offer protection against disease and grease buildup under and around your fingernails. Latex gloves are more comfortable but weaken when they are exposed to gas, oil, and solvents. Nitrile gloves are not as comfortable but they are not affected by gas, oil, and solvents.arrow_forward
