Based on the recent homework check (7 Lever Questions, as posted on the blog during the March Break):
8A had 10 with either incomplete work or work not able to be verified, not including absences
8B had 4 with either incomplete work or work not able to be verified, not including absences
8C had only 1 with either incomplete work or work not able to be verified, not including absences
The challenge question is due next class.
A 1kg mass is 10cm away from the fulcrum. Available for use are a 100g, 200g, and 500g mass. Use at least 2 blocks, not stacked upon each other, to balance out the Class 1 lever. Be sure to properly use formulae, substitution protocol, and include the correct units for your calculations.
Today in class you read about mechanical advantage; think about what is implied when MA = 1, < 1, and > 1.
