1. Compute the defection of a structural member made of aluminum if a load of 500 lb isapplied to the bar. The member has a uniform rectangular cross section with thedimensions of 1/4 in. x 4 in. as shown in the figure below.
2. The tire wrench shown below is used to tighten the bolt on a wheel. Given theinformation on the diagram, determine the moment about point O for the two loadingsituations shown:a. pushing perpendicular to the wrench armb. Pushing at a75º angle, as shown
3. Determine the moment created by the weight of the suspended sign about point O.Dimensions of the sign and the support are shown in the figure below. The sign is 2 mmthick and is made of aluminum (Unit weight 27 kN/m3)
4. Determine the sum of the moments created by the forces shown in the accompanying figureabout points A, B, C, and D,
We have used an experimental setup to determine the value of a spring constant. Thedefection caused by the corresponding weighs are given in the table below. What is thevalue of the spring constant?
