In the steel structure shown, a 6-mm-diameter pin is used at Cand 10-mm-diameter pins are used at Band D. The ultimate shearing stress is 154 MPa at all connections, and the ultimate normal stress is 400 MPa in link BD. Knowing that a factor of safety of 3.0 is desired, determine the largest load P that can be applied at A. Note that link BD is not reinforced around the pin holes. D Front view 18 mm 6 mm B. B Side view 160 mm 120 mm Top view The largest load P that can be applied at A is KN.

I want her Slove pls

Version B We have worked with Ferris Wheels above ground, but what if a portion of it went underground and traveled in a clockwise direction? Details; The Ferris Wheel has a diameter of 80 ft The Ferris Wheel center is 20 feet below the ground The Ferris Wheel rotates in a clockwise direction The rider enters on ground level on the right side of the wheel. It takes 1 minute for 1 ½ rotations. Your task: Determine the angular speed. Develop an equation for the height of the rider while on the ride. Calculate the rider's total distance traveled from the moment they get on at ground level on the right to the other point on ground level on the left where they get off.

solve, show all steps for given solution.
