A horizontal circular cylinder of diameter D = 0.2m and length 2m is elastically mounted on two springs and towing tank, as illustrated in the figure below. The cylinder is neutrally bouyant in water and the water density is 1000kg/m . The motion of the cylinder is only allowed in the crss-flow y direction. it is assumed that the three-dimensional end effects can be ignored, estimate the stiffness of the two identical springs which support the cyclinder
Note that the positive y direction is downward and counterclockwise torques are positive. find alpha the angular acceleration?
Apparent Density, Theoretical Density and Void Volume, A compacted body of iron powder is sintered into a 20mm-diameter, 45-mm-tall cylinder which, upon weighing
Why is it appropriate to take velocity measurements at several diameters downstream of the fan?
the light right-angle boom which supports the 400-kg cylinder is supported by three cables and a ball-and-socket joint O attached to the vertical x-y surface. Determine the reactions at O and the cable tensions.
A short 60-mm-diameter circular bar is made of a material for which the maximum safe compressive stress is 80 MPa and the maximum safe shearing stress is 30 MPa. Determine the maximum axial compressive force that can be safely applied.
What is the primary difference between the strength of a structure and the strength of a material? Is a strong material stiff?
