A train of four wheel loads 30 kN, 10 kN, 20 kN and 40 kN (distance between each sequential wheel is 1 m) is passing in the given order leading with 30 kN, from right to left on a simply supported girder of 10 m span. Which of these wheel loads should be placed at the section 2m from the left side support, to produce Maximum Bending Moment at that section?
When a series of wheel loads crosses a simply supported girder, the maximum bending moment under any given wheel load occurs when
There is only one rail track between stations A and B on a railway line. One hour after the northbound superfast train N leaves station A for station B, the southbound passenger train S reaches station A from station B. The speed of superfast train is twice that of express train E, while the speed of passenger train S is half of that of train E. On some one day train N leaves from station A to station B 20 minutes late than its usual schedule. Both Train N and Train S have increased their speed to maintain the schedule as per the table. If the superfast train doubles its speed, then what should be the ratio (approximately) of the speed of the passenger train to the speed of the superfast train so that the passenger train reaches the station on that day at the exact scheduled time.
Consider the following statements: 1. The thickness of the gusset plate should not be more than the thickness of the structural members being connected. 2. A plate girder is essentially a beam and its moment of resistance depends upon its section modulus. 3. The function of the flanges in a plate girder is to resist the bending moment and hence their respective areas can be reduced near the supports of a simply supported beam. Which of the above statements are correct?
In which of the following cases, there exists the situation of Pure Bending in some part of the beam or along the entire beam? i) A simply supported beam subjected to two equally spaced downward concentrated loads ii) A simply supported beam subjected to two equally spaced opposite moments iii) A cantilever beam subjected to clockwise moment at free end iv) An overhanging beam with both side overhangs subjected to different concentrated loads at both the free ends
A reinforced concrete beam is subjected to 5 kNm bending moment due to dead load and 25 kNm bending moment due to live load. What should be the design bending moment for limit state of collapse? 
Which of the following statements is true? A. Impact loads are equal to the sum of the magnitude of the loads actually caused and the magnitude of the loads had they been dead loads. B. Impact loads are equal to the difference between the above-mentioned entities.
The maximum bending moment under a particular load moving among the several moving loads on a simply supported beam occurs when that point load is placed
Each question presents a situation and asks you to make a judgement regarding that particular circumstance. Choose an answer based on given information. Three friends are waiting for a train on the railway station. Suddenly, a train passes by and each of them tries to remember the train number of the train written on each of the coaches. The train number was a 5-digit number. All must agree in order to confirm the digit of train number. 1. All three agrees that all the digits of the train number was different. 2. All three agrees that the difference of 3rd and 5th digit from left is equal to the 4th digit from the left. 3. All three agrees that the 1st digit was 1. 4. All three agrees that the 2nd digit was an even prime number. Which of the following would be most likely the train number?
The layout of a shaft supported on bearings at A & B is shown. Power is supplied by means of a vertical belt on pulley B which is then transmitted to pulley C carrying a horizontal belt. The angle of wrap is 180’ and coefficient of friction is 0.3. Maximum permissible tension in the rope is 3kN. The radius of pulley at B & C is 300mm and 150mm. If bending moment on point B in horizontal plate is M and in vertical plane is m, then the net bending moment at point B is?
