A spherical buoy used to mark the course for a sail- boat race is shown in the figure. There is a water current from left to right which causes a horizontal drag on the buoy; the effect of the current on the cable can be neglected.
The length of the cable between points A and B is 87 m, and the effective cable mass is 2 kg /m when the buoyancy of the cable is accounted for. Determine the tensions at both A and B.
Provide a plan view layout drawing of major components with key dimensions of your design in A3 size. Off the shelf components must be used where appropriate however the frame will be constructed in house to your design so you will need to accommod..
A thin spherica lshel'I has a radius of 1.90 m. An applied torque of 960 N.m gives the shell an angular acceleration of 6.20 rad/s2 about an axis through the center of the shell. What is rotational inertia of the shell about that axis?
