3) Calculations for the red dog food can rolling down the slope in the Rube Goldberg design are as follows (we will name it Step 1): DO Step 1 (calculations are given): Coefficient of friction → μ = 0.14 Mass of the object → m = 368 gm = 0.368kg Initial height of the object (red can on top of books) → h=8.89, cm = 0.0889 m Slope of the file folder → 0 = 14° Travelling Distance by the object = 11.5 inch = 0.292 m And length that the object will travel = h/sin 0 = 0.0889/ sin14° = 0.367 m So, the radius of the object → R = 0.367 -0.292 = 0.075 m Initial Velocity of red can → u=0 Velocity and Force Calculations for Step 1: -From total mechanical energy conservation: → Initial mechanical energy = final mechanical energy → mg - In case of pure rolling, the velocity of the center of mass: →→V=Ro=0.075 x 14.28 = 1.07 m/s. -Hence the change in force acting on the object for the travel: →F=mgsine = 0.368 x 9.81 × sin14° =0.89 N Step 2: The Selective Step (Step 2) in this design and for the…

Problem 3: Design engineers in many situations must justify their selection of beams and pin-ended columns used in various machines. Your role in a mechanical design company that manufactures gearbox and gearbox mounting platform is to analyse the rolled steel beams and columns under study. Your manager asked you to properly select one rolled steel beam and one rolled steel column for the design and to provide your justification of this selection, if the following design requirements are given: - Beams and columns are made of ASTM-A709/Grade-345 Factor of Safety (F.S) is 1.2 Buckling Euler conditions must be met. Beams are subjected to 50 kN axial force. Beam (A) has radius of 10 mm. Beam (B) has radius of 5 mm. Column (A) is subjected to 15 kN axial force. Column (A) has length of 1.5 m and radius of 10 mm. Column (B) is subjected to 15 kN axial force. Column (B) has length of 1.5 m and radius of 13 mm. P P A B Figure.3: Rolled steel beams. P P A P P Id B Figure.4: Rolled steel…

Hi, I have been given this pin-jointed frame analysis to solve (see pictures of the structure attached). Can you help me? The Figure 2 attached is a simplified structure to undertake a structural analysis on a concept design for a low cost stroller/buggy for children. The buggy consists of a number of metal sections that are pin-jointed together. The buggy is designed to accommodate a child of mass no more than 20 kg, sat on the seat which is supported at four points (Fc) on the frame of the buggy. Assume that the weight of the child is equally distributed across all of the points indicated on Figure 2 as Fc. Assume that there are no additional forces applied to the handle of the buggy, that the buggy is static (stationary) and that the buggy, and the elements of the frame have no mass. At points A and G, there are roll supports. At Points B, F and D there are the pin supports. I am required to determine the following: 1) Draw a free-body diagram of the structure 2) Simplify the Free…

Learning Goal: To analyze two built-up members that have the same geometry but are fastened differently, determine the maximum applicable shear force on each cross section, and determine the adjustment in spacing between the weaker member's fasteners that would allow the member to support the equivalent maximum shear force of the stronger member. The two cross sections shown below, (a) and (b), are subjected to a vertical shear force as shown. The members are fastened by nails that can support a load of 22.00 kN each and are spaced perpendicularly to the page in increments of s = 125.0 mm. The geometries of the cross sections are given by a = 235.0 mm, b = 50.00 mm, c = 225.0 mm, d = 135 mm, and e = 275 mm. Assume the cross sections are uniform along the entire lengths of the members. bk (a) Part A - Maximum applicable shear force on the member (a) *ak b 17 b ➜bk ➜bk Determine the maximum applicable shear force on the member (a).
