Solve Prob. 2–4 with F = 350 lb.

Step-by-Step Solution Step 1 We are given the value of force $F = 3{\rm{50 lb}}$. We are asked to estimate the magnitudes of the two components of F. Step 2 The relation to convert the force from pound into newton is, Since $1\;{\rm{lb}} = {\rm{4}}{\rm{.448}}\;{\rm{N}}$, then\begin{array}{c} 3{\rm{50 lb}} = \left( {350\;{\rm{lb}} \times \frac{{{\rm{4}}{\rm{.448}}\;{\rm{N}}}}{{1\;{\rm{lb}}}}} \right)\\ =

2–1. If u = 60 and F = 450 N, determine the magnitudeof the resultant force and its direction, measuredcounterclockwise from the positive x axis.

Step-by-Step Solution Step 1 Given that the angle $\theta $ is $60^\circ $, and the force $F = 450\;{\rm{N}}$. We are required to determine the resultant force and its direction measured counter clockwise from the positive $x$ -axis. Step 2 We have to make the parallel lines from the force vectors to get a parallelogram.
