Imagine a spring made of a material that is not very elastic, so that the spring force does not satisfy Hooke’s Law, but instead satisfies the equation F = −α x + β x3 , where α = 5.2 N/m and β = 700 N/m3 . Calculate the work done by the spring when it is stretched from its equilibrium position to 0.12 m past its equilibrium. Answer in units of mJ.

Consider a spring that does not obey Hooke's law very faithfully. One end of the spring is fixed. To keep the spring stretched or compressed an amount x, a force along the x-axis with x-component Fx=kx−bx2+cx3 must be applied to the free end. Here k=100N/m, b=700N/m2, and c=12000N/m3. Note that x>0 when the spring is stretched and x<0 when it is compressed. A)How much work must be done to stretch this spring by 0.050 m from its unstretched length? B)How...

A spring is found to not obey Hooke's law. It exerts a restoring force F(x) =-ax- 2 N if it stretched or compressed, where α = 60 N/m and β 18.0 Nm2/3. The mass of the spring is negligible. (a) Calculate the work function W(x) for the spring. Let U=0 when x=0. (b) An object of mass 0.900 kg on a horizontal surface is attached to this spring. The surface provides a friction force that is dependent on distance Fr(x)2x2...
Engineers have invented a new kind of spring whose restoring force is proportional to the third power of displacement
Engineers have invented a new kind of spring whose restoring force is proportional to the third power of displacement: |F(x)| = |βx3| where B = (1/9) N/m3. One end of this spring is fixed to the bottom of an inclined plane which makes an angle θ = 36.87° with respect to the horizontal, and the other end is stretched up the incline and attached to a block of mass m = 3.00 kg. The spring is initially stretched a distance...

2. A mass of m kilograms (kg) is mounted on top of a vertical spring. The spring is L metres long when disengaged and the end not attached to the mass is fixed to the ground. The mass moves vertically up and down, acted on by gravity, the restoring force T of the spring and the damping force R due to friction: see the diagram below The...
