Total mass (block plus masses) | 0.1029 kg | 0.1529 kg | 0.2529 kg | 0.302.9 kg | 0.3529 kg | 0.402.9 kg |
Normal Force | 1.01 N | 1.50 N | 2.48 N | 2.97 N | 3.46 N | 3.95 N |
fsmax | 0.06 * 9.8 = 0.588 N | 0.13 * 9.8= 1.27 N | 0.225 * 9.8 = 2.21 N | 0.305 * 9.8 = 2.99 N | 0.31 * 9.8 = 3.04 N | 0.38 * 9.8 = 3.72 N |
Mass of hanger plus masses | 0.06 kg | 0.13 kg | 0.225 kg | 0.305 kg | 0.31 kg | 0.38 kg |
From your measurements and analysis, and your understanding ofthe maximum static frictional force, can you come up with anequation that describes how fsmax depends on the normalforce? Hint: Is fsmax proportional to the normal force?Is fsmax proportional to the normal force squared?etc.
What is the proportionality constant? Â Â
What are its units?
Does the proportionality constant make sense in terms of thematerials of the block and horizontal surface? Explain.
