The small-remotely controlled robotic vehicle of Probs. 5/177 and 5/178 is shown again here. The 200-m tether has a slight negative buoyancy in that a net downward force of 0.025 N per meter of its length acts on it. Using its onboard variable horizontal and vertical thrusters, the vehicle maintains the constant 10-m depth as it moves slowly to the right. If the maximum horizontal thrust is 10 N and the maximum vertical thrust is 7 N, determine the maximum permissible value of the distance d and state which thruster is the limiting one.

Problem. 5/177

A small remotel y-controlled underwater robotic vehicle and its tether are positioned as shown. The neutrally buoyant vehicle has independent thrusters for horizontal and vertical control. The tether, designed to be very slightly buoyant, has a net upward force of 0.025 N per meter of its length acting on it. There are 60.5 m of cable between points A and B. Determine the horizontal and vertical forces which the vehicle must exert on the cable at B in order to maintain the configuration shown. Also, find the distance h. Assume that the tether between points A and B is entirely under water.

Problem. 5/178

The remotel y-controlled robotic vehicle of Prob. 5/177 is now connected to a 200-m tether which has a slight negative buoyancy in that a net downward force of 0.025 N per meter of its length acts on it. Determine the horizontal and vertical components of thrust which must be produced in order to hold the vehicle in the position shown. The vehicle itself is neutrally buoyant.
