$R = \sqrt\mathbfR_x^2 + \mathbfR_y^2 = \sqrt(186.60)^2 + (223.21)^2 = 291.15$ N
$\theta = \tan^-1 \left( \frac\mathbfR_y\mathbfR_x \right) = \tan^-1 \left( \frac223.21186.60 \right) = 50.11^\circ$
The final answer is: $\boxed291.15$
Problem 1-5
The cable and pulley system is used to lift a weight $W$. Determine the tension $T$ in the cable.
Meriam’s solutions always begin with a clearly drawn FBD. If your FBD omits a reaction force or includes an extra force, your equilibrium equations are worthless. The solution manual trains you to scrutinize every contact and support.
Not entirely. Meriam 8th edition renumbered many problems and added new ones. However, problems that appear in both editions have the same solution approach, though the numerical values may differ. $R = \sqrt\mathbfR_x^2 + \mathbfR_y^2 = \sqrt(186
$\mathbfRx = \mathbfF1x + \mathbfF2x = 86.60 + 100 = 186.60$ N $\mathbfRy = \mathbfF1y + \mathbfF2y = 50 + 173.21 = 223.21$ N
Did you mis-align a force? Did you forget a couple moment? Before looking at the full solution, check only the first step of the solution manual.
Engineering Mechanics Statics J.L. Meriam 8th Edition Solutions is a powerful academic tool—but only if you respect its purpose. It is not a replacement for attending lectures, drawing free-body diagrams from scratch, or struggling through a difficult equilibrium problem at 2 AM. Further Resources:
When used as a learning aid, the solutions manual demystifies Meriam’s rigorous problem-solving style. You will learn to see 3D vector geometry, recognize two-force members at a glance, and sum moments about clever points to eliminate unknowns.
Remember: Every licensed professional engineer once struggled with these same Meriam problems. The difference between a struggling student and a successful engineer is not innate talent—it is the willingness to check, correct, and re-solve until the method becomes second nature.
Use your solution resources wisely. Master the concepts. And soon, you will not need the solutions manual at all—because you will think like Meriam intended. Have a specific Meriam problem you are stuck on
