What does the “Knit Surface” feature do in SolidWorks?

• Joins multiple surfaces into one

• Adds thickness to a surface

• Trims overlapping surfaces

• Creates a copy of surface at a specified distance 

What happens to the density of an object if its volume increases, but mass remains constant? 

• Density increases

• Density decreases

• Cannot be determine

• Density remains the same

How does a drip plate contribute to workplace safety?

• By reducing valve noise

• By preventing fluid from dripping onto valve body

• By increasing the valve's pressure rating

• Drip plate acts as a sunshade for valve body

What is the function of a hydraulic pump?

• To regulate the flow of hydraulic fluid 

• To convert mechanical energy into hydraulic energy

• To compress air for storage

• To filter impurities from the hydraulic fluid
