Question

Shown below is a simplified model of an emersion blender. A pair of rectangular cutting blades 5mm×2mm×50mm are centered to the shaft end and a set of frictionless bearings simply support the shaft to mitigate the bending moment at the motor connection:に2cm and = 14cm. An electric motor provides torque with sufficient power to overcome the chunky liquid at the optimal speed of 300rpm. Thick soup produces a drag moment proportional to the operating speed of the blades, assume this damping constant to be c=0.2Nm. Also while operating, assume that chunky food could produce an impact force of Foa 100N actig at the ends of each blade simultaneously, and that two additional loads are possible: wr 50N&Fle 50N caused by liquid suction and side flow Paper Design: size and identify an appropriate electric motor and determine the shaft diameter using preferred sizes and a factor of safety of 2.0 under max loading conditions.
