Set 5 - Tutorial building the machine design called " Discovery" The best way to learn is to do it. Below are the step by step instructions to make a creation with Set5. We have many tutorials that can deeply explore mechanical motion & machines.
Step 1- Screw in the Posts. The post position is identified by column, alphabetically from left to right. The student finds the column and then counts down the required number of holes to identify the correct post hole. The correct unit length post ( 1U, 2U, 3U, 4U, 5U or 6U) is then inserted. "Discovery" required 11 posts in total. Post positions and unit length are given below. A8-2U, C13-3U, D5-3U, F8-1U, G3-3U, K5-1U, K10-5U, N4-4U, O12-3U, Q5-4U and Q9-4U.
