Testing stress in shaft in Mechanica

I'm having trouble running a Mechanica test on a shaft. The version of Pro/E I have only has Mechanica Lite. Here's a picture of the shaft. It's supported at the bearings shown and the rotor in the middle rotates. I want to study the stress in the shaft under the weight of itself and the rotor and under torsion from the rotor spinning.

I've opened Mechanica Lite from the shaft part file, but was unable to constrain properly where the bearings would be or apply the moment properly. The best thing I could think of was to add blocks as shown below that would act to support the shaft and that would essentially serve as the bearings. In the testing. I was able to constrain these blocks.

Now I'm trying to apply a moment, but the moment option is greyed out no matter what I select (shown below). I'm also unsure how to apply gravity. I would appreciate help in running this analysis. My end goal is to see how much I can hollow out the shaft to save on weight and maintain strength. Thanks.
