Simple harmonic motion and static equilibrium
Ok, I must not know how to do it correctly because I'm getting it to equal zero for all time. Solving the equation you gave me: x(t) = C2 sin(sqrt(a) t) + C1 cos(sqrt(a) t) = 0 using the initial conditions C2 = 0 , C1 = 0 as such, x(t) = 0 for all time- oceanwalk

Simple harmonic motion and static equilibrium
Homework Statement In static equilibrium a spring is stretched 0.25 m by a hanging mass. If the system is initially moved up to the unstretched position and released with zero velocity, determine position of the mass (in m) after 4.2s. Take the equilibrium position to be zero and up the...- oceanwalk

Solid Mechanics - Force in a bolted assembly
A bolted assembly consists of a steel bolt A, a brass tube B and a nut C. The nut is turned so that it just secures the tube, and then is tightened one extra turn. Determine the resulting force Fs (in kN) in the steel bolt. The initial length of the tube is L = 158 mm, and the screw pitch is 1mm...- oceanwalk
