- 14. A spring stretches 7 cm when a 1.2 kg mass is suspended from it. What is the spring constant? Energy of a Mass-Spring System: Class Work 15. A mass of 1.4 kg is attached to a horizontal spring with a spring constant of 75 N/m. The spring is stretched from equilibrium position by 5 cm and released. a. What is the maximum elastic potential ...
- The maximum compression produced in a spring of force constant k, when a block of weight W moving with velocity v on a frictionless horizontal surface compresses it, shall be: A v k W

?A block having a mass of 0.80 kg is given an initial velocity v A = 1.2 m/s to the right and collides with a spring of negli- gible mass and force constant k = 50 N/m, as shown in Fig- ure 8.12. (a) Assuming the surface to be frictionless, calculate the maximum compression of the spring after the collision.to same force. Equivalent stiffness (k) = k1 + k2 = 24 N/mm. QUESTION: 2. A compression spring is made of music wire of 2 mm diameter having a shear strength and shear modulus of 800 MPa and 80 GPa respectively. The mean coil diameter is 20 mm, free length is 40 mm and the number of active coils is 10. If the mean coil diameter is reduced to 10 ...Lumen gameVariables in Hooke's Law Equation. F s = spring force. k = a spring constant. x = displacement. The equation can also be stated: F = k x. Where F is the force exerted on the spring, k is the spring constant and x is the displacement. You might see this equation in the case where the problem is in determining what is the force pulling on or ....

- Known: A machine uses a pair of concentric helical compression springs to support a known static load. Both springs are made of steel and have the same length when loaded and when unloaded. Find: Calculate the deflection and the maximum stress in each spring. Schematic and Given Data: F = 3.0 kN do di Di Do Do = 45 mm do = 8 mm No = 5 Ni = 10 ...
