A 8 mm thick mild steel plate is connected to a 10 mm thick plate with single lap joint by 16 mm diameter shop rivets. What is the number of rivets required to carry 180 kN load? (Hint: permissible stress of rivet in shear mode = 100 N/mm2 and permissible stress of rivet = 300 N/mm2)

If the internal dimensions of a ware house are 15 m x 5.6 m and the maximum height of piles is 2.70 m, then the maximum number of bags to be stored in two piles is

An identified source of irrigation water has ion concentrations of Na⁺, Ca⁺² and Mg⁺² as 22, 12 and 7 milli equivalents per liter, respectively. The SAR of this water is

A 1000 kg automobile is driven down a 5 incline at a speed of 80 kmph, when the brakes are applied, causing a total braking force of 5.8 kN to be applied to the automobile. Determine the distance travelled by the automobile before coming to rest in meter.

A hydraulic structure is to be designed for 40 years return period. The design team allows a maximum risk of failure of 30%, The maximum design life of the structure is

A prestressed concrete beam of 8-meter beam span has a cross section dimension of 300 mm × 400 mm. It is prestressed by parabolic tendon as shown in the figure below. Calculate the maximum intensity of uniformly distributed load (in kN/m) that it can carry (inducing self-weight), so that no tension is produced throughout the beam.

A thin walled hollow shaft with an internal diameter of 100 mm and an external diameter of 120 mm is subjected to a torque of 50 kNm. The magnitude of shear flow in the shaft is

A three-hinged parabolic arch of span 30 m are supported at unequal level as shown in the figure below.

The arch carries a point load of 40 kN at a distance of 10 m from extreme right support and an uniformly distributed load of 10 kN/m on the left span. The horizontal thrust at support A is _____.
