Design the tab to be welded to the hopper for connection to the support straps, as shown in Figure. The hopper load is 15.0 Mg. The material from which the hopper is made is ASTM A36 steel. Specify the width and thickness of the tab and the design of the welded joint. You may want to coordinate the tab design with the bolted connection called for in Problem.

Problem

Design the joint at the bottom of the straps in Figure if the total load in the hopper is 15.0 Mg. Use steel bolts and a bearing-type connection. Specify the pattern, number of bolts, bolt diameter, bolt material, strap material, and strap dimensions. You may want to coordinate the strap design with the results of Problem. The design of the tab in Problem is also affected by the design of the bolted joint.

Problem

Design the joint at the top of the straps in Figure if the total load in the hopper is 15.0 mega-grams (Mg). The beam is a WT12X34 made of ASTM A36 steel and has a web thickness of 10.6 mm. The clear vertical height of the web is about 275 mm. Use steel rivets and specify the pattern, number of rivets, rivet diameter, rivet material, strap material, and strap dimensions.
