1. A frame of a hydraulic rivetter is shown below in the figure with I cross-section. A load P = (last two digts of your student ID) kN is applied. A ductile material of yield strength, Sy = (350 + last two digits of your student ID) MPa is used. Use a factor of safety, n = 3.0 and find the dimensions of I cross-section. Use appropriate theories of failure and state clearly all your assumptions. If your student ID = 2021005345, P = 45 kN and Sy = (350+45) MPa = 395 MPa. 120 mm (16) 15t-↑ 7t

4. Describe the dimensions: design quality and conformance quality.

Multiple choice questions, please help thank you!! 1. The chemical potential (μ) of smaller size clusters is bigger than that of bigger size clusters because of  (a) their small size  (b) the fewer number of atoms in them (c) surface area is smaller (d) their surface is more curved 2. Which of these characteristics would you associate with SEM: A surface imaging tool Maintained under vacuum Provides imaging and compositional data Uses a scanned electron beam All of the above   3. Secondary electrons (SE) are best described as Low energy electrons from the sample surface  High energy electrons from the sample surface  Low energy primary beam electrons  High energy primary beam electrons 4. Atomic force microscopy (AFM) is the most widely used form of scanning probe microscopes for the characterization of nanomaterials since it require: (a) electrically conductive and optically transparent samples (b) neither electrically conductive nor optically transparent samples (c) electrically…
