There are two ways to join wheels onto designs. First method is to use wheels connected through an axle. An axle should connect two wheels, unless wheels will not operate. To secure the axle, there are washers on both surfaces of the wheel, and a nut which acts as a "lock nut". An axle can either go through your design or go underneath it.
Another method is to use caster. Caster includes a bracket, and it is secured by screws, which are drilled from the bottom side of the bracket. This is joined with the bottom surface of the design. It looks like this:
In terms of Paper 1, I reckon annotating these features with 2D drawings will be fine. However, if you are confident enough, I recommend including these features to your isometric drawing.
I have attached an image to show you how to show wheels onto your design for paper 1.
II. Pop riveting steps/stages
As you learnt in class, pop riveting is a common process used to quickly and permanently join metal sheets (mainly). When using pop rivets, a pop rivet gun and pop rivet is used, which looks like this:
I will try to explain all steps in pop riveting with details.
Drill a hole with the correct size through a metal sheet, then insert a pop rivet.
Place the pop rivet gun over the pop rivet's mandrel.
Squeeze the pop rivet gun's handle. This will pull the rivet head up through the pop rivet, up to the surface of the material to be joined.
Then the pin/mandrel breaks, completing the rivet.
I have attached a Resistant Materials textbook to help you revise for RM Paper 3. The content about pop riveting process starts from page 119.
Hi Owen, thank you for your question.
