- Question 5. The diagram below shows a mass suspended from a tie supported by two horizontal braces of equal length. The tie forms an angle "a" of 60° to the horizontal plane, the braces form an angle 0 of 50° to the vertical plane. If the mass suspended is 10 tonnes, and the braces are 10m long, find: a) the force in the tie; & b) the force in the braces Horizontal Braces, Tie Massarrow_forward= MMB 241 Tutorial 2.pdf 1 / 3 75% + + Tutorial z Topic: Kinematics of Particles:-.

- A beer still is being used to separate ethanol from water at 1.0 atm. The saturated liquid feed flow rate is F = 840.0 kmol/h. The feed is 44.0 mol% ethanol. The saturated vapor steam is pure water with ratio of steam flow rate S to feed rate, S/F = 2/3. We desire a bottoms product that is 4.0 mol% ethanol. CMO is valid. Find the mole fraction of ethanol in the distillate vapor, yD,E. Find the number of equilibrium stages required.
