Problems: all but 1A & 1B from Ambrose & Tripeny, Chapter 1 & 2, pgs 18, 20, 25, and 85.
1A) Determine the weight in newtons (N) of a car whose mass is 1550 kg. Convert the mass
of the car to kN and then determine its weight in pounds and kips. (No figure.) (conversions)
Partial answer to check with: 15,205.5 N
1B) You are given two measurements off a non-dimensional ruler of A = 8.69 and B = 1.427
marked in 100ths (0.01). Knowing the accuracy of the data you are given, determine the
quantities of A+B, A-B, AxB and A/B with reasonable precision. (math & precision)
Partial answers to check with: A+B = 10.1, AxB = 12.4 (by significant digits)
Problem 1.3.B,D,F. By constructing the parallelogram of forces, determine the resultants for the
pairs of forces shown in Figures 1.5 b, d & f. (graphical addition)
Partial answers to check with:
Rb = 121 lb,
d = 22° below +x,
Rf = 57 lb
Problem 1.3.I. Using graphical methods, find the resultant of the system of concurrent forces
show in Figure 1.7 (i). (graphical addition)
