If you needed to choose a polymer to do FFF/FDM, how would you rank the following properties in terms of how important they would be to the FFF/FDM process and the subsequent use of what you printed. Using bullets briefly explain what each property is and why the property it is where it is in your ranking. List the most important property first. a. Density
b. Elastic modulus
c. Coefficient of thermal expansion
d. Melting
e. Temperature and Glass
f. Transition Temperature

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
