Find the spring constant if a 20. N force stretches a spring 2.0 m.

The dimensions are of the graph are d1 = 7 cm , L1 = 6 m , d2 = 4.2 cm , and L2 = 5 m with applied loads F1 = 130 kN and F2 = 60 kN . The modulus of elasticity is E = 80 GPa . Use the following steps to find the deflection at point D. Point B is halfway between points A and C. What is the reaction force at A? Let a positive reaction force be to the right.

Statics an 2.18 A 200# stone is being lifted off the ground by a lev- ering bar. Determine the push P required to keep the stone in the position shown. Varignon's Theorem The French mathematician Pierre Varignon developed a very important theorem of statics. It states that the mo- ment of a force about a point (axis) is equal to the algebraic 1W=200* 3011 36" 47

Those data are for ouestions 12.136 14. The slender 8-kg bar AB is horizontal and at rest. The spring has an unstretched length sọ of 1 mand a spring constant of 15 N/m. the length of the bar AB is l-1.5m - - Find the elastic energy due to the spring when the bar has rotate clockwise 0 - 45° after being released. Give your answer with 2 decimals.

Just need help and explanation on this question, wasn't discussed in class. Thanks!

2. Find the Force reading on the spring scale. Show all your work and box the answers. Step 1 is to draw a Free Body Diagram and Step 2 is to sum the Forces in the X& Y. Use the diagram included. N is the Normal Force, Tis the Tension and Wis the Weight. Spring Scale प्री- .T 100 Ib 20° W N

please provide all the steps and show as much work as posible. Thanks!

igure 2. Assume that the rod is massless, perfectly rigid, and pivoted at point P. When the rod is perfectly horizontal, the angle 0 = 0, the displacement y 0, and the springs are in neither tension nor compression. Gravity acts on the system (e.g. on mass M). We assume that y is a small displacement. A mass M is attached at the end of the rod. DE only 225 Your tasks: X k 0 3k a F a M y A Derive an equation of motion for the system in terms of the angular displacement 0, and its derivatives (you should not have y or its derivatives in this equation.)

Could you help me solve only FEA, FBA, and FCA. I've made a mistake in the calculation but I don't know what. Could you work it out? So only the force equilibrium in point A. F = 200N. All are 2 force members.
