The segments of pipe and couplings used for drilling an oil well 15,000 ft deep are made of A-36 steel weighing 20 lb/ft. They have an outside diameter of 5.50 in. and an inside diameter of 4.75 in. Determine the force P needed to remove the pipe, excluding friction along its sides and requiring F = 0. Also, what is the elongation of the pipe as it just begins to come out?
A force is specified by the vector F= 120i-160j+80k lb. Calculate the angles made by F with the positive x-,y-, and z- axes.
The rod is fixed against rotation at its left end, but free to rotate in a bearing at its right end. Each disk is 300mm in diameter. Calculate the maximum shear stress in each segment of the rod.

what should be the minimum radius of curvature p for the track at B so that the passengers do not experience a normal force greater than kmg?neglect the size of the car and passengers.Take k=4
The outer surface of the tank is cooled by air at 300 K with a heat transfer coefficient of 100 W/m2K. Determine the maximum temperature in the tank. Take the thermal conductivity of the wastes as 2.0 W/mK.
The block has a mass of 150 kg and rests on a surface for which the coefficients of static and kinetic friction are 0.5 and 0.4, respectively. If a force F = (60t^2) N, where t is in seconds, is applied to the cable, determine the power developed ..
The frame is supported in part by normal and friction forces between the wall and the plate at A. Determine the friction force exerted on the plate at A. Also determine the minimum required coefficient of friction at A for the frame to remain in e..
