Engineering Mechanics: Statics is a comprehensive textbook that systematically builds the foundational principles of statics, integrating key concepts from vector analysis to equilibrium conditions of particles and rigid bodies. The book progresses from basic notions like force vectors and free-body diagrams to advanced topics such as moment calculations, structural analysis, and virtual work methods. It emphasizes a logical, step-by-step approach to problem-solving, ensuring that students master techniques such as dimensional homogeneity, integration for distributed loads, and the application of Newton’s laws. Overall, the text equips readers with both theoretical insight and practical tools essential for effective engineering analysis and design.

Problem 4
The bar is supported by the spring and smooth collar that allows the spring to be always perpendicular to the bar for any angle $\theta$. If the unstretched length of the spring is $l_{0},$ determine the force $P$ needed to hold the bar in the equilibrium position $\theta .$ Neglect the weight of the bar.

Problem 5
The tractor exerts a towing force $T=400 \mathrm{lb}$. Determine the normal reactions at each of the two front and two rear tires and the tractive frictional force $\mathbf{F}$ on cach rear tire needed to pull the load forward at constant velocity. The tractor has a weight of 7500 lb and a center of gravity located at $G_{T}$, An additinal weight of 600 lb is added to its front having a center of gravity at $G_{A} .$ Take $\mu_{\mathrm{s}}=0.4$ .The front wheels are free to roll.
Problem 6
The members of a truss are pin connected at joint $O$ Determine the magnitudes of $\mathbf{F}_{1}$ and $\mathbf{F}_{2}$ for equilibrium. $\operatorname{Set} \theta=60^{\circ}$.
