HW04 General Notes : Dynamic analyses are based upon FBDs; thus, all situations and calculations involving forces require FBDs as discussed in class. FBDs will form a portion of the required points for all problems of this type through the end of the semester , regardless of whether they are specified in the problem statement. 1. Wolfson, Ch. 4 #45. Use the problem situation (changing 12N to 15N) and calculate all normal forces on all blocks and the system acceleration. 2 . Wolfson, Ch. 4 #53. Change 4300kg to 4900kg. f) Moving forward with constant speed. Many students wonder why Dr. Hasty makes such a big deal about coordinate systems and their utility. To illustrate the importance of (and rationale for) selecting ‘efficient’ coordinate systems, consider a simple situation: a 11kg crate slides from rest without friction 9.5m down a ramp inclined 12.5° below horizontal. In the two cases below, the same calculations will be performed using different coordinate systems. Place the coordinate origin upon the crate as it begins moving.
