Question

Hello sir, I want a line of solution to have the same picture. I attached a picture for you, please sir, I want himself, please

Home Work:
1. As shown in figure below, a hole is to be punched out of a plate having an
ultimate shearing stress of (300MPA)
1) If the compressive stress in the punch is limited to (400MPA), determine the
maximum thickness of plate from which a hole (100mm) in diameter can be
punched.
2) If the plate is (10mm) thick, compute the smallest diameter hole which can be
punched
Solution:
1) Thickness = 33.33 mm
2) Diameter = 30 mm

Solution:
5 m
5 m
a)
Given data:
The diameter of the cable is d = 0. 6 in
%3D
• The weight of the bar is w =
6000 lb
b)
Consider the triangle DAB,
AB=/(5 m)² + (3 m)²
=V34
Taking moment at about point C,
E M.=0
5T + 10(T)=5(6000 lb)
3
V34
5T + 5. 144T=30000 lb
T=2957. 13 lb T=2957.13 lb
c)
The expression to calculate the stress is given as,
T
A
2957.13 lb
7(0,6 in)?
=10458. 72 psi

Your capstone design team is prototyping (e.g. you are building a model to test not a final product) a "fire identification drone. The final product is intended to fly over rugged wilderness areas and look for small fires that should be monitored and potentially fought or contained. It is NOT intended to be used in large active fires. Your subteam's job is to design and build the support frame for the drone (e.g. the structure where the motors, propellers, guidance electronics and GPS, heat sensors, radio receiver and transmitter, etc. are attached) for the prototype. You have access to a machine shop with saws, lathes (for removing material by rotating it and using a cutting tool), drills and a facility with 3-D printers that can print a variety of plastics using fused deposition modeling (this is the technique where a polymer filament is melted and forced through a nozzle to build a structure layer by layer). You will be testing in a summer/fall timeframe so you expect temperatures…
Consider the solid model design of piston picture (a). You have been assigned a task to manufacturethis piston based on the following methods:-a. Sand Castingb. Any other manufacturing method of your own choicec. Draw the complete engineering-based comparison between the adopted method of your ownchoice and sand casting for manufacturing the piston. Your comparison must include theeffectiveness of manufacturing method, stresses-based analysis in manufacturing methods,product finishing, time laps for completing the product, cost effectiveness of methods, laborcost analysis.d. How can you measure the surface roughness of the piston surface highlighted in picture (b),based on your previous knowledge of manufacturing processes? You must have to mention theequipment by which you will measure its roughness and write the accuracy level. You mustdraw a valid reason for selecting that equipment.Take the dimensions of piston at your own but take more realistically.
