Description : A muff coupling is connecting two shafts. The torque involved is 650N-m. The shaft diameter is 45mm with length and height of the key being 14mm and 80mm respectively. Find the compressive stress induced in the key. a) 70.1 N/mm2 b) 51.6N/mm2 c) 45.5N/mm2 d) None of the listed
Last Answer : b) 51.6N/mm2
Description : Solve : `(2n + 3)/(6n -5) = 1`
Last Answer : Solve : `(2n + 3)/(6n -5) = 1`
Description : What is the first 5 terms of the sequence with nth term 6n-1?
Last Answer : 5, 11, 17, 23, 29
Description : How do you evaluate -5( 6n plus 6) 30?
Last Answer : If you mean -5(6n+6) = 30 then -30n -30 = 30 and so n = -2 whenevaluated
Description : What city 6n 80e?
Last Answer : 6 N 80 E is the Laccadive Sea. The nearest city is Colombo, thecapital of Sri Lanka.
Description : If a body weighs 12N on the surface of the earth, how much will it weigh on the surface of the moon where acceleration due to gravity is only one-sixth of that on earth's surface? (1) 12N (2) 2N (3) 10N (4) 6N
Last Answer : (2) 2N Explanation: Weight is mass x g. Since mass is constant and g is only 16thof that on the earth. The weight on the moon is only 16th of that on the earth.
Description : A concentric spring consists of 2 sprigs of diameter 10mm and 4mm. The net force acting on the composite spring is 5000N. Find the force acting on each of the two springs. (a) 1232.2N and 3767.8N (b) 786.4N and 4213.6N (c) 689.7N and 4310.3N (d) 645.3N and 4354.7N
Last Answer : (c) 689.7N and 4310.3N
Description : Find the shear stress in the spring wire used to design a helical compression sprig if a load of 1200N is applied on the spring. Spring index is 6, and wire diameter 7mm. a) 452.2N/mm² b) 468.6N/mm² c) 512.2N/mm² d) None of the listed
Last Answer : b) 468.6N/mm²
