Figure I shows a configuration of the spreader bar based on the model number stated in Table 1. You have to design a bracket that will hold the spreader bar. The bracket will be mounted on 45 deg slanting platform of lifting mechanism. Based on the given dimensions stated in Figure 1. you have to design a simple bracket comprises of two plates, plate A and B as shown in Figure 2. Plate A will hold the spreader bar and it is welded to plate B. Plate B will be bolted to the platform. Your task is i) to design the simple bracket. The dimensions of bracket can be roughly estimated based on the dimensions stated in Figure 1. Model number of the spreader will be assigned in the class. ii) to determine the most critical situation when the lifting process is carried out. State all of assumptions and you must set the safety factor iii) to select the welding electrode to be used and calculate the size of weld required. iv) to set the arrangement of the bolted joints and calculate the size required based on the selected bolt class.
