High-strength bolts are used in the construction of many steel structures. For a 1-in.- nominal-diameter bolt, the required minimum bolt tension is 51 kips. Assuming the coefficient of friction to be 0.30, determine the required couple that should be applied to the bolt and nut. The mean diameter of the thread is 0.94 in., and the lead is 0.125 in. Neglect friction between the nut and washer, and assume the bolt to be square-threaded. You must show a free body diagram of your block and incline analysis of the bolt and nut, and clearly indicate your force triangle, if any.
A steel ramp is used by a worker in a factory to move a cardboard box. The box weighs 40 lb with a center of gravity at point G, the force applied by the worker is parallel to the ramp and the coefficient of friction between the box and ramp is μs = μk = 0.3. Determine the value of the normal force N. Determine the force the worker must apply to slide the box up the ramp. Determine the friction force F acting between the ramp and the box if the worker slid the box up the ramp. Determine the force the worker must apply to slide the box down the ramp. Determine the friction force F acting between the ramp and the box if the worker slid the box up the ramp.
(a) A body of weight 45 N is placed on a rough horizontal plane. To just move the body on the horizontal plane, a push of 30 N inclined at 11° to the horizontal plane is required. Find the coefficient of friction. (b) Determine the number of members in a structure, if the total number of joints in the structure is 6.
In the vise shown in the figure, the screw is single-threaded in the upper member: It passes through the lower member and is held by a frictionless washer. The pitch of the screw is 3 mm, its mean radius is 12 mm. and the coefficient of static friction is 0.15. Determine the magnitude P of the forces exerted by the jaws when M= 74-N.m couple is applied to the screw. Assuming that the screw is single-threaded at both A and B (right-handed thread at A and left-handed thread at B) The value of magnitude P is KN? Note: please consider everything. Refer to the image for more clarity. On occasions, I receive wrong answers!!. Kindly please show the magnitude of P which is the final answer in " KN" in the step by step working out please. Appreciate your time!. Side note, the answer in the image is wrong. This question is very annoying!. And a lot of experts have given me wrong answers!. So I beg to show concise working out!. Also I've attached another image something to help with…
Two identical wood blocks with weight W are being pushed apart by a wedge. The coefficient of static friction for all surfaces is 0.325. Determine the weight of the wedge, P, required to start the blocks moving. The wedge is symmetrical about the vertical, and 0 = 24°. Use the triangle method or the component method. urgenttt thank you

An arrangement of three boxes is shown in figure below. Box A weighs 25 N and rests on an inclined plane, while box B weighs 50 N and rests on a horizontal plane. The coefficient of friction between box A and the inclined plane is 0.3, and between box B and the horizontal plane is 0.4. The pulleys are all frictionless. Determine the range of weight of box C for which no motion will occur. Consider both sliding and tipping of boxes A and B. 0.6 m 0.75 m 25 N 5 A 4 C pome 0.8 m 0.6 m 50 N B 1.2 m
