1. Refer to the sketch #1 below and the text book Cal Trans wind table on page 54, Table 3.2 to determine the following: a. Draw a Free Body Diagram (FBD) of this wind load on the 70 ft high pier/rebar cage. Show the Resultant Forces and all applicable dimensions. b. Determine the location of Rtotal from the base of the pier/rebar cage c. If a support (reaction) point was connected 50 ft from the base (where shown on sketch), calculate the value of the horizontal force at this connection location
