Design of the Toggle Jack. Lifting load – W, kN is 8 Distance between nuts– B, mm is 50 - 280 Types of threads is Square Length of the links, mm is 140

please very urgent with count the number of link and full joint and pin joint (J1-J2) on all the graph

If you have a roller pin on its side connected to a beam, will it have a vertical reaction or just a horizontal reaction? Or both?

RB&W11 recommends turn-of-nut from snug fit to preload as follows: 1/3 turn for bolt grips of 1-4 diameters, 1/2 turn for bolt grips 4-8 diameters, and 2/3 turn for grips of 8-12 diameters. These recommendations are for structural steel fabrication (permanent joints), producing preloads of 100 percent of proof strength and beyond. Machinery fabricators with fatigue loadings and possible joint disassembly have much smaller turns-of-nut. The RB&W recommendation enters the nonlinear plastic deformation zone. The figure shows a cross section of a grade 25 cast-iron pressure vessel, with a torque factor K of 0.09. Use Eq. (8-27) to estimate the torque necessary to establish the desired preload given that preload F;= 14.4 kip, bolt stiffness kb = 5.21 x 106 lbf/in, number of threads N=11, and material stiffness km = 8.95 × 106 lbf/in. in-11 UNCX 2 in grade 5 finished hex head bolt in in 162 No. 25 CI Determine the torque necessary to establish the desired preload and the turn of the nut in…
