Brinell Hardness Test Quiz

What is the primary purpose of the Brinell hardness test?

• To assess the ductility of a material

• To evaluate the tensile strength of a material

• To determine the hardness of a material

• To measure the elasticity of a material

Which components are located in the upper part of the testing machine?

• Control panel and monitor

• Support table and microscope lens

• Indenter and digital camera

• Test piece holder and control knob

What is the function of the support table in the Brinell hardness testing machine?

• To hold the microscope lens

• To adjust the height of the test piece

• To display the hardness value

• To rotate the indenter

What is the first step in preparing for the Brinell hardness test?

• Programming the control panel

• Inserting the test piece into the machine

• Adjusting the support table height

• Selecting a suitable spherical indenter

How is the test piece positioned correctly for the Brinell hardness test?

• By focusing the digital camera

• By moving the control panel

• By adjusting the support table height

• By rotating the indenter

What happens when the start button is pushed during the Brinell hardness test?

• The microscope lens rotates to its resting position

• The test piece is removed from the machine

• The control panel displays the hardness value

• The indenter is inserted into the holding device

How does the testing machine apply the test force to the test piece?

• By rotating the test piece

• Gradually and shock-free

• Suddenly and with a shock

• By moving the control panel

What is the next step after the indenter lifts off the test piece?

• The hardness value is displayed

• The test piece is removed

• The control panel is reset

• The microscope lens pans back to its former position

How is the diameter of the indentation measured?

• By estimating visually

• By using a digital caliper

• By placing measuring lines on the edges of the indentation

• By using a ruler

How is the Brinell hardness value calculated?

• Test force multiplied by the area of the indentation

• Test force divided by the diameter of the indentation

• Test force divided by the area of the indentation

• Test force multiplied by the diameter of the indentation
