Calculate the velocity v of the collar as it hits the stop at B if it is elevated from rest at A by the action of the constant 40-N force in the cord. The cord is guided by the small fixed pulleys.
A bullet is fired horizontally into a wood block resting on a horizontal, frictionless surface. If the mass of the bullet is 0.02 Kg and the velocity is 600 m/s
Mainframe computing used to be the only way to manage enterprise data. Then personal computers changed the data management scene. How do these two computing styles differ, and how did shift to PC-based computing evolve.
Determine the heat transfer coefficient for laminar flow over this cylinder. First, at your discretion, select an available set of experimentally obtained data from the literature. Then, this would provide you with a set of Reynolds numbers.
determine the time needed for the velocity to become v=vf. initially the particles falls from rest.
Determine Compressor Size in Watts that is suitable to satisfy certain specific needs, The drinking water needs in a production facility with 20 employees is to be met by a water bubbler type water fountain.
Wind turbines are becoming more and more common as a method of energy production, wind turbines by their very nature are dynamic and are subject to and create their own internal and external kinematics and kinetics.
determine diameter of a circular rod of ductile material with a fatigue strength ,e=280 Mpa. Add a tensile yield strength of 350 Mpa. The member is subjected to a varying axial load from 700 kN to -300kN. Assume Kt=1.8 and factor of safety=2.
