A full journal bearing has a journal diameter of 37 mm, with a unilateral tolerance of -0.012 mm. The bushing bore has a diameter of 37.05 mm and a unilateral tolerance of 0.032 mm. The bearing is 74 mm long. The journal load is 2 kN, and the journal runs at 575.831 rev/min. Using an average viscosity of 55.6 mPa-s, find the minimum film thickness, the maximum film pressure, and the total oil-flow rate for the minimum clearance assembly. The minimum film thickness is The maximum film pressure is The total oil-flow rate for the minimum clearance assembly is mm. Mpa. mm³/s.

Use the following paragraph to answer the question below. Robotic arms can have different end effectors. An end effector is the attachment that is put on the end of the robotic arm. An end effector may be a claw tha can pick things up and place them. Other end effectors include a welding tool and a drill. What is the main Idea of this paragraph?

Summarise and discuss the general strategies to select CAD/CAM software and tools for Computer Aided Process Planning (CAPP) and optimisation of design and manufacturing operations, especially to generate optimal CNC machining toolpaths, simulate the generated CNC machining toolpaths, create G-Code programs for CNC machining operations, simulate and optimise the Additive Manufacturing & 3D Printing (AM-3DP) processes (Topology optimisation, Simulations of support generation, Simulations of deformation and shrinkages, Simulations of Nesting operation, Optimisations of part orientations).

Explain why you should use RAC and what its main characteristics are.
