Determine the torque required from the base link on link 2 for static equilibrium of the mechanism shown below. Force F has a magnitude of 20 Ib. (Use scale 1in = 2 lb). Construct a mechanism! rz = 2 in B2 on 2 B, on 4 Ts = 2 in T4 = 4 in To20, = 1.5 in 6. 30 De

Q1 (а) A tall standpipe as shown in Figure Q1(a) with an open top has an inner diameter 7 d=2.1 m and wall thickness t= 20 mm, Given the weight density of water y = 9.81 kN/m³ and water pressure is p = y h, calculate the height h of water that will produce a circumferential stress of 12 MPa in the wall of the standpipe. (i) (ii) Calculate the axial stress in the wall of the tank due to the water pressure.

Part I. Shorter problems focused on the fundamentals a. For the image at the right, the coordinate angles are a = 57°, ẞ= 121°, y=49°, and the point along a-a is (15,-6,3). What is the angle between lines a-a and b-b? Z b-b B LL F a (x,y,z) a-a Y b. If the magnitude of the force, F-3121bf, what is the magnitude projected along the a-a axis? y

The class I'm taking is physics for scientists and engineers! I need help with parts E,F,G PLEASE I am completely stuck. Need help. I have attached the problem. Please view both attachments before answering. If you can please explain your answer so I can fully understand. Thank you!
