ables 1 (5 points) Experimental Mass (kg) Force Force (N) Direction 0.050 20.00 90.0 0.100 Equilibrant FEL Resultant FRI 70 Graphical Solution Force (N) Direction Force Fi 0.49 20.0 90.0o Resultant FRI Analytical Solution Force (N) Force rection LX-component component 13 90.00 Part 1: Error Calculations (12 points) Error of magnitude for Experimental compared to Analytical 2.03 Error of direction for Experimental compared to Analytical Error of magnitude Graphical compared to Analytical Error of direction Graphical compared to Analytical cos 20

Explanation / Answer

Table 1 .
(1) % Error of magnitude of experimental with analytical
= ((Experimental force - Analytical) / Analytical force )*100
= (1.254 - 1.28) /1.28)*100 = -2.031
(2) % error of direction of experimental with analytical
   =  ((Experimental - Analytical) / Analytical )*100
   = (70 -68.1)/68.1)*100 = 2.79 %
(3) % Error of magnitude of graphical with analytical
  =  ((Graphical force - Analytical) / Analytical force )*100
  = (1.254 - 1.28) /1.28)*100 = -2.031 %
(4)% error of direction of experimental with analytical
= ((Graphical - Analytical) / Analytical )*100
= (69- 68.1)/68.1)*100 = 1.321 %.
