A system of connected flexible cable shown in Fig.3 is supporting two vertical forces 200 N and 250 N at points B and D. Determine the forces in various segments of the cable.
A gusset plate of roof truss is subjected to forces as shown in Fig.2. Determine the magnitude of the resultant force and its orientation measured counter clockwise from the positive x-axis.
The resultant of the two forces, when they act at an angle of 60o is 14 N. If the same forces are acting at right angles, their resultant is √137 N. Determine the magnitude of the two forces.
A ball of weight Q=12lb rests in a right angles trough, as shown in figure B.Determine the forces exerted on the sides of the trough at D and E if all surfaces are perfectly smooth.
An aeroplane is flying at 21·5 m/s at a low alti- tude where the velocity of sound is 325 m/s. At a certain point just outside the boundary layer of the wings, the velocity of air relative to ...Read more
0.3 Kg of Nitrogen gas at 100 kPa and 40°C is contained in a cylinder. The piston is moved compressing nitrogen until the pressure becomes 1 MPa and temperature becomes 160°C. The work done during the process is ...Read more
