Can you help me with a matlab code? I am trying to plot the keplerian orbital elements over time. I would usually find the orbit using cartesian system and then transform into keplerian orbital elements. Is there a way to directly integrate keplerian orbital elements?

The combined weight of the acrobat and his balancing pole is 900 N, and the friction between his shoes and the rope is large enough to prevent him from slipping. Neglecting the weight of the rope and any elastic deformation, determine the deflection (y) and the tension in portion AC and BC of the rope for values of x from 0.5 m to 10 m using 0.5 m increments. 1. Determine the maximum deflection (y) in the rope. 2. Plot tension of AC and BC vs. x (on the same plot with x on the x-axis). Turn in the plot and the table of x, TAC, and TBC (clearly label each).

The bar is supported at end A by a ball joint such that it carries only a compressive force along its axis. The bar is supported in equilibrium at end B by cables BD and BC that connect to the xz plane at points C and D respectively with coordinates given in the figure. The z components of the moments exerted on the bar by these two cables sum to 0. The tension in cable BD is measured to be 210 Newtons. Input answers of zero as 0.00 to avoid an invalid answer due to significant figures.
