- How can acoustic-assisted 3D printing revolutionize the production of microscale mechanical components and devices?arrow_forwardThe theoretical failure strength is significantly higher than the empirical failure strength of polycrystalline materials, even when they are highly polished because: a) Polycrystalline materials have little or no capacity for plastic deformation, so they have lower failure stresses b) Plastic deformation in polycrystalline materials adsorbs energy which reduces their failure strength c)The energy needed to break the atomic bonds in crystal lattices is lower in polycrystalline materials as compared to in single crystals d)Polycrystalline materials contain internal discontinuitiesarrow_forwardtwo cylinders are printed on a 3d printer, with a setting of 40% fill rate. This means that the solid parts of the cylinders at 40% plastic material. Given this, tell me how much plastic material is used to make each of these cylinders. I measured both cylinders in meters and these are the measurements below A) Cylinder 1- Height: 0.042m Radius 2(outer radius): 0.008m Radius 1(inner radius): 0.006m B) Cylinder 2 Height: 0.022m Radius 2(outer radius): 0.008m Radius 1(inner radius): 0.006marrow_forward
- What are the benefits of examining and experimenting with a model rather of a physical thing or situation?arrow_forwardB7arrow_forwardTwo students decided to print a prototype for a gear. Student A use layer thickness of .1 mm and an infill density of 25%. Student B use a layer thickness of 0.07 mm and an infill density of 45%. Which student will take less time to print the gear? Select one: Stu nt since the ckness of layer is smaller and the infill density is higher. O We can't decide which process takes less time O Student A since the thickness of the layer is larger and the infill density is lower. Student B because thickness is higher than B and the infill density has no effect on the process speed. Student A because thickness is higher than B and the infill density has no effect on the process speed.arrow_forward
- Which equation will yield a direct solution to problems involving force,velocity and time?arrow_forwardEach time constant of an exponential curve is equal to what percentage of the whole?arrow_forward[Please Write Clean and Provide Complete Explanation] One end of a 2 m long steel rod (d = 3 cm) is rigidly attached to a wall so that the rod is perpendicular to the wall. The other end of the rod is welded to a second rod, which is 1 m long (d = 1.0 cm). The second rod is parallel to the wall and the floor. A vertical force of 50 N is applied to the end of the second rod. For both rods, the modulus of elasticity is 210 × 109 Pa and the shear modulus is 79 × 10 9 Pa. There is an infinitesimally small cubic element at the top surface of the 3 cm diameter rod immediately adjacent to the wall, that is, at (0, 1.5, 0). What is most nearly the maximum normal stress due to the bending moment?arrow_forward
