The mirror housing of the telescope is supported by a 6-bar space truss. the mass of the housing is 3 mg (megagrams), and its weight acts at g. the distance from the axis of the telescope to points a, b, and c is 1 m, and the distance from the axis to points d, e, and f is 2.5 m. if the telescope axis is vertical what are the axial forces in the members of the truss?

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
