Design a zero off-set plate cam with an harmonic rise, cycloidal rise, and a 3-4-5 polynomial fall with the following data: Cam specifications: - Harmonic rise (0° < θ < 90° ) from 0 mm to 15 mm - Dwell ((90° < θ < 120° ) - Cycloidal rise (120° < θ < 180°) from 15 mm to 25mm - Dwell (180° < θ < 240°) - 3-4-5 polynomial fall (240° < θ < 360°) from 25mm to 0mm. The cam is driven by a constant speed motor rotating counter-clockwise at 250 rpm The radius of the base circle = 45 mm The radius of the roller follower = 6 mm

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
