A 1000 kg, 4 meter long beam is suspended by two cables at its ends. The beam is holding up a 1250 kg

submersible probe, which is suspended 1 meter to the right of the left cable. The submersible is underwater,

and its volume is 0.75 cubic meters. The density of water is 1.00×10^3kg per cubic meter.

1. What is the tension in the cable supporting the submersible? (Note: there is a buoyant force at play here!)

2. What are the tensions in the left and right cables supporting the beam? (Don't forget to account for the weight of the beam!)
