7-34. The beam is constructed from three boards. If it is subjected to a shear of V = 5 kip, determine the maximum allowable spacings of the nails used to hold the top and bottom flanges to the web. Each nail can support a shear force of 500 lb. 0 0 10 in. 1.5 in. 12 in. V 1 in. 6 in. 1.5 in.

The average normal stresses developed in section a a of the turnbuckle, and the bolts shanks at B and C, are not allowed to exceed 15 ksi and 45 ksi, respectively. Determine the maximum axial force P that can be applied to the turnbuckle. Each bolt shank has a diameter of 0.5 in.

Please show your complete solution. Thank you! The truss is loaded by a 4-KN force and a 5-KN force applied at B and A, respectively.Determine the magnitude of axial force developed in members CE and CF.

P 62.5 mm Key 55° The cast iron block with cross-sectional dimensions of 62.5 mm by 62.5 mm consists of two pieces. The pieces are prevented from sliding along the 55° inclined joint by the steel key, which is 62.5 mm long. The working stresses are 275 MPa for cast iron in bearing and 345 MPa for the key in shear. If the block is loaded with P= 282 kN, calculate the required dimension "b" of the key. Write your final answer in 2 decimal places with the unit of mm.

Problem #2: Determine the internal axial force in each member of the truss using the force method. Clearly indicate whether the member is in tension or compression. Assume AE is constant. Hint: When cutting extra member(s), recall that the "cut primary" truss still must transmit the load to the supports and must be stable! Thus, selecting which members to cut should be trivial here! 3m -4 m- B -4 m C E 8 KN -4 m- D

Please sovle this question in handwritting step by step.

The question and detials are provided on the image attached, thank you!

It is obtained by fixing 4 wooden planks to each other with nails.given as a cross section. 2 verticals forming the sectionplank 20 mm X 80 mm, the other two planks 20 mm X 120 mmin size. between the nails fastening the planksthe distance is s = 50 mm. allowed on each nailThe safe cutting force is 300 N.a) The highest vertical that the beam can safely carryWhat is shear force?b) The maximum amount formed in the section corresponding to this shear force.What is high shear stress?

Show your work neatly please!
