Assignment #5 Due date: Nov 14 th 2015 1. You have a 4 bar linkage to design here. The base frame has hinges at 𝑥 = 0 and 𝑥 = 6 . Given link lengths are 𝑙 2 = 4 , 𝑙 3 = 6 and 𝑙 2 = 5 . The coupler is a constant thickness constant volumetric density equilateral triangle of side 6 units and mass 20 units with negligible sized holes for hinge joints at its two vertices. Find mass and position of centre of mass for both the driver and follower link so as to balance the 4 bar linkage while operation. 2. A small scale steam turbine operating at 3000rpm experienced violent vibrations after a year of operation. Testing engineers confirmed mass unbalance as the root cause for the dangerous event. You were invited as an engineering consultant to solve the problem. The testing engineer told that the centre of mass of a 120kg rotor at 1.5m along the axis from the inlet guide vanes shifted 2mm away from the axis. You can only access two planes, one axially .5m before the inlet guide vanes and the other axially .5m from the last turbine blade at the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
