4. For the composite block shown, determine (a) the value of h if the portion of the load carried by the aluminum plates is half the portion of the load carried by the brass core, (b) the total load if the stress in the brass is 80 Mpa.

A Charpy V notch test was conducted for an ASTM A572 Grade 50 bridge steel. The average values of the test results at four different test temperatures were found to be: 10 ft.lb at -50 degrees F 15 ft.lb at 0 degrees F 40 ft.lb at 40 degrees F 50 ft.lb at 100 degrees F The bridge will be located in a region where specifications require a minimum of 25 ft.lb fracture toughness at 30 degree F for welded fracture-critical members. If the bridge contains a welded flange in a fracture-critical member, does the steel have adequate Charpy V notch fracture toughness? Show your supporting Calculations. Only attempt when you are sure ,else skip for others , otherwise I will downvote for wrong answers

REACTION OF A RIGID PLATE II A) Determine the internal and external reaction forces of a composite structure. To check the solution you will need to specify reaction components Ax, Az, Ma, Bx, Bz (body II), Cx, Cz (body III), Dx, Dz, Ex, Ez (body IV), Fx, Fz (body V), G (force transmitted by the member gj), H (force transmitted by the member hj), Kx, Kz. coefficient's are a= 1,1 b= 0,6 c=1.1
Which of the following statements is true? O Welded joints have the advantage of cost and simplity O Bolted joints are stronger but more expensive O Welded joints are stronger but more expensive O Bolted joints have the advantage of cost and simplicity
As shown in the figure below, a bronze bar is affixed between a steel bar and an aluminum bar. Axial loads are applied at the positions indicated. If the largest value of P that will not exceed an overall deformation of 4.0 mm, or the following stresses: 150 MPa in the steel, 130 MPa in the bronze, and 90 MPa in the aluminum, determine the stress in the bronze. Assume that the assembly is suitably braced to prevent buckling. Use Est = 200 GPa, Eal = 70 GPa, and Ebr = 83 GPa. (The correct answer is 71.36 MPa. Can you show the solution? Thank you!)
1. Three metal strips, each 40 mm height, are bonded together to form the composite beam shown. The modulus of elasticity is 210 GPa for the steel, 105 GPa for the brass, and 70 GPa for the aluminium. If the allowable bending stress for the aluminum (Gallow)al= 100 MPa, for the steel (Gallow)st 150 MPa and (Gallow)br=200 MPa for brass determine the maximum allowable intensit of w of the uniform distributed load. 2w 2m Aluminum Brass Steel 40 mm- 10 mm 10 mm 20 mm
