What does negative thermal strain indicate? Choose the two best options.

Temperature difference results in the expansion of the given body.

Reference temperature is greater than that of the applied temperature.

Reference temperature is lower than that of the applied temperature.

Temperature difference results in the contraction of the given body.

What is the location of Maximum Equivalent stress obtained from the simulation for the lifting arm part below?

D

C

B

A

5 / 10

Review the Direction Deformation in the y-direction and select the best option below that is a correct statement.

The lifting arm assembly is expanding due to the high temperatures imposed on the structure.

The lifting arm assembly is being stretched due to the large load applied on the bottom.

Despite the applied load, the lifting arm assembly is contracting due to the assembly having temperatures less than 900 ºC, which is the environment or reference temperature.

The lifting arm assembly is expanding due to the high temperatures and is further stretched from the applied load.

6 / 10

Review the Reaction Force at the support at the belt location. Why is there a non-zero reaction force in the z-direction? Select the best option.

The lifting arm assembly will have a tendency to bend, so it is expected that the reaction forces develop in the z-direction to counter this bending.

The support at the belt location shares an edge with the Symmetry Region.

The force is applied in the y-direction, but the geometry causes a small portion of the forces to react in the z-direction.

The temperatures cause non-zero reaction forces in the z-direction.

7 / 10

Review the Direction Deformation in the y-direction. Assume that the Force due to the weight of the gears is ignored. (Do not re-run the simulation.) Select the best option below that is a correct statement about the new scenario.

No conclusion can be made without re-running the actual simulation.

No changes to the deformation would occur.

The lifting arm assembly would contract more in the y-direction.

The lifting arm assembly would expand more in the y-direction.

8 / 10

If the user decides to take advantage of symmetry and decides to solve the quarter model, which of the following options suit best as magnitude of applied force for the current scenario?

75,000 N

37,500 N

100,000 N

150,000 N

9 / 10

650 ºC

750 ºC

450 ºC

550 ºC

10 / 10
