Pipe (2) is supported by a pin at bracket c and by tie rod (1). the structure supports a load p at pin b. tie rod (1) has a diameter of 11 mm and an allowable normal stress of 85 mpa. pipe (2) has an outside diameter of 42 mm, a wall thickness of 3 mm, and an allowable normal stress of 150 mpa. assume x1 = 3.0 m, x2 = 2.0 m, and y1 = 4.2 m. determine the maximum load pmax that can be supported by the structure without exceeding either allowable normal stress.

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?

Which of the following best describes internal energy? a. the difference between the kinetic and potential energies of the particles in a system b. the sum of the kinetic and potential energies of the particles in a system c. the sum of the kinetic and thermal energies of the particles in a system d. the difference between the kinetic and thermal energies of the particles in a system
