- A special-purpose eye boll with a shank diameter d - 0.50 in. passes through, a hole in a steel plate of thickness tp = 0.75 in. (see Figure) and is secured by a nut with thickness t = 0.25 in. The hexagonal nut bears directly against the steel plate. The radius of the circumscribed circle for the hexagon is r = 0.40 in., so each side of the hexagon has a length 0.40 in. The tensile Forces in three cables attached to the eye bolt are T1= 800 lb, T2= 500 lb. and T3= 124 lb. (a) Find the resultant force acting on the eye bolt. (b) Determine the average bearing stress crhbetween the hexagonal nut on the eye boll and the plate. (c) Determine the average shear stress T aver in the nut and also in the steel plate.A small lab scale has a rigid L-shaped frame ABC consisting of a horizontal arm AB (length b = 10 in.) and a vertical arm BC (length c = 7 in.) pivoted al point B. The pivot is attached to the outer frame BCD that stands on a laboratory bench. The position of the pointer al C is controlled by a spring, Jt = 5 lb/in., that is attached to a threaded rod. The pitch of the threads is p = 1/16 in. Under application of load W, 12 revolutions of the nut are required to bring the pointer back to the mark. Calculate the weight W.A bicycle chain consists of a series of small links, where each are 12 mm long between the centers of the pins (see figure). You might wish to examine a bicycle chain and observe its construction. Note particularly the pins, which have a diameter of 2.5 mm. To solve this problem, make two measurements on a bicycle (see figure): (1) the length L of the crank arm from main axle to pedal axle and (2) the radius R of the sprocket (the toothed wheel, sometimes called the chainring). (a) Using your measured dimensions, calculate the tensile force T in the chain due to a force F = 800 N applied to one of the pedals. (b) Calculate the average shear stress T averin the pins.
- Figure 8-19 is a cross-section of ASTM A36. A total of N bolts are to be used to resist a separating force of 7258.97N is one bolt. A) Determine kb,km, and C B) Determine the realized load factor for overload, the yielding factor of safety, and the load factor of joint separation.QUESTION: Suppose a bolted tension used in a doube-D ring configuration is properly preloaded. The spring constant for the bolts is 7.8 MN/m and the spring constant for the members is 12.7 MN/m. By how much does the tensile force in the bolt increase when a load of 705 N is applied? You may assume that joint separation does not occur. Give your answer in units of NFor the same question, the M25 Screw will be used when pressing the Nut Wheel onto the shaft. Assuming that the force that the nut needs to suppress is Fçak=1218 kgf (it was found in the previous question, but we don't use it), what should the minimum NUT HEIGHT be in mm to create this force safely? (Screw and Nut's surface safety pressure Pem=45 N/mm2 Screw base diameter d1= 21.5 mm. (Calculate the pitch (h=?) according to the given ones, considering that metric screw is used!)
- Pls give right answer with step by step explanation. Design a clamp coupling for a shaft diameter of 60 mm. The torsional moment to be transmitted by this coupling taking in to account over loading as 160 N-m. The number of bolts used are 6 and the allowable stress in the material of the bolt is limited to 5N / m * m ^ 2 . The coefficient of friction between the shaft and muff material is 0.25.The forces shown in the following figure act on a specific screwed part. It can be noted that none of them acts directly on the known x and y axes. With this, what should be the force component acting on these axes? Options: a) The force on the x-axis is 20.54 N; and on the y-axis, it is 250.22 N. B) The force on the x-axis is -20.54 N; and on the y-axis, it is 230.22 N. c) The force on the x-axis is -22.54 N; and on the y-axis, it is 190.98 N. d) The force on the x-axis is 21.20 N; and on the y-axis, it is -234.89 N. e) The force on the x-axis is -20.54 N; and on the y-axis, it is 250.22 N.1. A jack having square threads of 50 mm nominal diameter and 10 mm pitch is supporting a load of 89 kN. A double thread is used and the coefficient of friction maybe as low as 0.10 or as high as 0.15.a. Will this screw always self-locking?b. What is the highest torque necessary to raise the load?
