At the instant shown in Figure 4, the m-kg bar rotates clockwise at 5 rad/s. The spring attached to its end always remains vertical due to the roller guide at C. The spring has an unstretched length of ln and a stifness of k-N/m. Propose the stiffness of the spring k and the mass of the bar m when the bar achieves 1 rad/s at angular 25". The ratio between the length of the spring when the bar is at 25° and the unstretched length lan is 2. Draw the free body diagram (FBD) to indicate what you have mentioned in the solution.

Problem- Cargo ships can cause a lot of air pollution.Solution- to use nuclear powered ships since they hold a lot of energy and can travel for long distances. How it will work is that it will need a nuclear reactor at the bottom of the boat to heat up the water and then turn it to electricity to power the boat. The boat will be made out of graphene which is a tough material to avoid any leaks in the boat. It will also contain many control rods because nuclear power is so powerful that it can create to much energy to handle. With control rods, you can slow down this process and keep it in a controlled manner. Since cargo ships are already is the ocean, there will be no need for any extra materials to make it work. -Do you think this will work? Why/Why not? -What do you think is wrong with it/ How can this be improved? Please send this to someone else I need to record 50 responses for a science project. Thank you!
