A bracket is welded to the verical column by means of two fillet welds as shown in the figure. Determine the size of the welds, if the permissible shear stress in the weld is limited by 70N/mm^2.

A cylindrical tank with hemispherical heads is constructed of steel sections that are welded circumferentially (see figure). The tank diameter is 1.1 m, the wall thickness is 32 mm, and the internal pressure is 12 MPa. Determine the maximum shear stress in the cylindrical tank. Welded seams Lutfen birini seçin 8.75.89 MPa b. 62 50 MPa C. None d. 22.67 MPa e 103 13 MPa

The capital cost of a hydro-power station of 50 MW capacity is Rs 1,000 per kW. The annual depreciation charges are 10% of the capital cost. A royalty of Re 1 per kW per year and Re 0·01 per kWh generated is to be paid for using the river water for generation of power. The maximum demand on the power station is 40 MW and annual load factor is 60%. Annual cost of salaries, maintenance charges etc. is Rs 7, 00,000. If 20% of this expense is also chargeable as fixed charges, calculate the generation cost in two part form.
