Machine parts designLaajuus (5 cr)

Objective

On completion of the course, the student will be able to calculate stresses under combined loading in frame structures. The student will be able to compute stresses in thin-walled profiles. The student will be able to calculate deflections in trusses and frames with an energy method and assess the stresses under impact loads. The student will be able to choose and calculate a hydrodynamic journal bearing, spur gear drive, planetary gear drive, coupling for rotating shafts, and brake motor.
