A rigid pavement is designed to carry a static wheel load of 60.0 kN. If the allowable flexural stress of the PCCP is 1.40 MPa, determine the minimum thickness that can be safely used. Assume no dowels are used across the joints. 2. Repeat previous problem; assume sufficient dowels are used across the joints

STATİC I need the answer within 1 hour. Thanks Rod AB is secured from point B with a cable and from point A with a smooth, up and down movable collar. Calculate the tensile strength generated in the BC cable. ? = {−??} N direction is -z a(m)=15.75 , b(m)=13.5 , c(m)=8.55 d(m)=3.75 F(N)=61.5

3. Calculate the critical load of a strut which is made of a bar, circular in section and 5 m long and wheh is pin-jointed at both ends. The same bar when freely supports gives mid-span deflection of 15 mm with a load of 85 N at the center.

QUESTION 2 A 13-kN hydraulic press for removing and reinstalling bearings in small-to medium-sized electric motors is to consist of a commercially available cylinder mounted vertically in a C- frame, with dimensions as sketched in the Figure shown below. It is being proposed to use ASTM A-48 (Class 50) gray cast iron (brittle material with ultimate strength, Su 345 MPa) for the C-frame material. Calculate the bending moment about the centroidal axis upto 3 digits after decimal point in KN.m? 18 mm 38 mm 13 kN 25 mm 10 mm -90 mm 10 mm 1.805 Save A Click Save and Submit to save and submit.
