The figure shows a rigid lever arm CBA that is pinned at A and connected to a wire at B. An applied force P causes the lever arm to rotate 0.05 degrees counterclockwise. What is the strain in the wire? P 300 mm C В A -400 mm-

The figure above is a skycam which is supported by 2 wires (assume that no wires holding at the top of this device). Assume that the wires are 0.05 inches diameter. If the skycam weighs 77 lbs, then the tensile stresses of wire 1 and wire 2 are Blank 1 ksi and Blank 2 ksi respectively.  SN= 77

MKOPO The piece of rubber is originally rectangular. Calculate the average shear strain Yxy at A if the corners B and D are subjected to the displacements that cause the rubber to distort as shown by the dashed lines. 3 mm- D 400 mm A 300 mm- B 2 mm X

The 16 x 22 x 25-mm rubber blocks shown are used in a double U shear mount to isolate the vibration of a machine from its supports. An applied load of P = 238 N causes the upper frame to be deflected downward by 4 mm. Determine the shear modulus G of the rubber blocks. Double U anti-vibration shear mount 25 Rubber block dimensions Shear deformation of blocks O 0.745 MPa O 0.883 MPa O 1.140 MPa

The beam cross section shown below has been proposed for a short pedestrian bridge. The cross section will consist of two pipes that are welded to a rectangular web plate. Dimensions of the cross section are: h = 390 mm tw = 12 mm d = 100 mm t = 6.4 mm Additionally: • The area of each pipe is A = 1882 mm². • The moment of inertia of the entire beam cross section about the z centroidal axis is lz=171660000 mm4. If the beam will be subjected to a shear force of V = 120 kN, determine the shear stress at point H, located at yμ = 100 mm above the z centroidal axis. H Hv K Answer: TH= X MPa Ун Ук K Iv
