Modeling the spring

Perform the following steps for modeling the spring:

1. Add (Shift + A) a cylinder and change its dimensions to the dimensions of the measured spring when extended (remembering the measured by typing the diameter followed by a /2, and blender will divide it by 2 and give the radius.) In the example the diameter was 3.8mm or 1.9mm for the radius and the depth was 13.2mm.

2. Add (Shift + A) another cylinder changing the depth to the length of the compressed spring, 5.3 in the example. Name these objects Springextended and Springcompressed. The internal measurement will be important later but unused in this step.

   

3. Hide (H) the spring shapes for later.
