To determine The flow rate of water stream from the faucet. Explanation Apply Bernoulli’s equation for the top (1) and bottom (2) of the water stream. p 1 γ + V 1 2 2 g + z 1 = p 2 γ + V 2 2 2 g + z 2 (I) Here, pressure at points 1 and 2 are p 1 and p 2 , velocity at points 1 and 2 are V 1 and V 2 , acceleration due to gravity is g , elevation at points 1 and 2 are z 1 and z 2 , specific weight is γ . The pressure of the stream is constant, p 1 = p 2 . The elevation at point 1, z 1 = 0.5 m . The elevation at point 2, z 2 = 0 m . Write the continuity equation. Q = A 1 V 1 = A 2 V 2 V 1 = Q A 1 V 2 = Q A 2 Here, the flowrate is Q and area are A 1 and A 2 . Rewrite Equation (I) using the above. ( Q A 1 ) 2 2 g + z 1 = ( Q A 2 ) 2 2 g ( Q A 2 ) 2 − (

A block of mass m hangs from the end of bar AB that is 7.2 meters long and connected to the wall in the xz plane. The bar is supported at A by a ball joint such that it carries only a compressive force along its axis. The bar is supported 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. Cable BD is elastic and can be modeled as a linear spring with a spring constant k = 400 N/m and unstretched length of 6.34 meters. Determine the mass m, the compressive force in beam AB and the tension force in cable BC.
