The required diameter for the round member AB to resist only the bending action of the force P (use a factor of safety F.S.=2). The diameter of the pin C‚ also made of A-36 steel‚ so it acts as a fail-safe mechanism to limit the loading of the member CD to 75%

Statics and Dynamics 1. The diagram below shows the loading on one of the horizontal floor beams and associated supporting vertical columns for a proposed building‚ sited on an incline. In order to consider the worst case‚ assume that the beam is simply supported and the column is pin jointed at either end. 1.1 Determine the beam reaction forces at each support and . Taking moments around (2 x 50) + (6 x 70) + (10 x 20) = (8 x ∴ = = 90 KN So‚ = 50 + 70 + 20 = + 90

Solids | | Adam McCreevey | 3/15/2013 | This is a laboratory to learn how to make measurements using a strain gauge by using different configurations‚ also to determine experimentally the axial and transverse stress at the surface of the beam and compare them to theoretical calculations | Introduction If a length of wire is subject to a stress within its elastic limits‚ the resulting elongation and change of diameter alters the resistance. The resulting principle is used in the resistance

The primary tools for the lab consisted of 10 ceramic tiles and a Instron machine. The Instron machine was initially set up for 3-point bending by a technician. The base and thickness of the tile was then measured. Following that the length of the ______ was measured. Next‚ the Instron machine was set to 50 lb/min and 5 tiles was tested using 3 point bending. The max load to fracture in lb was recorded for each tile. Then‚ the Instron machine was set up for 4
