A train having 20 wagons weighing 18 tonnes each is to run at a speed of 50 kmph. The tractive effort of a 2-8-2 locomotive with 22.5 tonnes load on each driving axle is 15 tonnes. The weight of locomotive is 120 tonnes. Rolling resistances of wagons and locomotive are 2.5 kg/tonne and 3.5 kg/ tonne respectively. The resistances which depend upon the speed. Are computed as 2.65 tonnes. Find out the steepest gradient for these conditions.

An extra flexible 8 × 19 steel wire rope of 38 mm diameter is used with a 2 m diameter hoist drum to lift 70 kN of load. The wire rope has a length of 900 meters. The maximum speed is 3 m / s and the acceleration is 1.5 m / s2. The diameter of the wire may be taken as 0.05 d, where d is the diameter of wire rope. The modulus of elasticity of the entire rope is 84 × 103 N/mm2. The weight of the rope is 53 N/m length. Determine the effective load during acceleration of load in kN.

In calculating the magnitude of load in a distributed load system Select one: a. the length to the center of gravity is considered b. the length to the centroid is only considered C. the portion where distributed load is applied is considered d. The length of all body is taken in consideration. OO Shot by Hisense H12

Equivalent single wheel load of a dual assembly carrying 35 kN each is 62 kN at a depth of 30 cm. Calculate the distance between the walls of tyres (in cm) if the centre to centre spacing between the tyres is 20 cm. (Answer upto 2 places of decimal).

3: An equipment works on a road with a sandy clay soil with coefficient of traction (0.42). - Find the maximum force can be provided by this equipment before sliding the driving tires. If the total weight on the driving wheels is (25 ton)? - What is the maximum coefficient of traction that the equipment can work with it if the maximum force of its engine is 12000 Kg, for the same weight?
