Rigid member ABC is supported by a wire BD at B and a pin support at C as shown below. The failure stress in the pin at C and wire BD are tfail = 250 MPa and Ofail = 350 MPa, respectively. Apply a factor of safety (FS) = 3 to determine the value of the maximum force P that can be applied. The pin at C is in double shear. Dpin at C 3 (mm) Dwire BD 2(mm) 40°, P D 30° В 400 mm 600 mm 300 mm

Measuring site work, Excavation and Piling

Bid drawings typically include very little material about the precise requirements of site work operations, measuring site work and excavation work differs from measuring most other works on a construction project. The actual site work conditions are not provided and also the dimensions of the excavations are not known during the pre-construction phase. The precise measurement of the excavation and backfill of the earth material and topsoil is important for a contractor to decide upon the total cost required for the process. All the works should be carried out under OSHA (Occupational Safety and Health Administration) standards to ensure the safety of the workers.
