22.The smaller of two concentric helical springs is made of 22 mm diameter steel spring andhas an outside diameter of 100 mm with 10 active coils. The outer spring is made of 32 mm steelspring and has an outside diameter of 250 mm with 8 active coils. Before load is applied, theouter spring is 25 mm longer than the inner spring.If the load is 90 KN is applied to this rest ofsprings.Find the rate of each spring.A. 507.5 KN/m, 143.6 KN/mC.493.8 KN/m, 126.5 KN/mB. 731.5 KN/m, 212.5 KN/mD.976.1 KN/m, 318.8 KN/m

4. The system on the right consists of three solid circular cross-section rods 1, 2 and 3. All are made from the same material with a Young's modulus of E. Forces 2P and P act at connectors C and D. Assume that as the system deforms, the connectors C and D are allowed to translate but not rotate. Assume the weight of the rods is small compared to the loads and can therefore be neglected. 1. Is this system determinate or indeterminate? 2. Write down the equilibrium force and momentum equations for connectors C and D hint: draw the FBD for C and D 3. Write the elongation equations relating the elongations to axial loads for each the three rods. 4. Write down the compatibility equations relating the elemental elongations in the rod system. 5. Solve for the axial loads in each element. State whether each element is in tension or compression. 2d (3) 3L 2P P D L 2L (2) 4d C (1) 4d B

a helical compression spring with squared and ground ends is ti be made of a steel wire 79 gpa and presetting is to be used. the operation load of the spring can be considered static. If the maximum working force is 292 N and a force of 35 N is required when the spring is 30 mm longer, determine the spring constant k
Question 1 A 125 kg electric motor and a 505 kg reciprocating compressor are mounted on a common support. The motor runs at 2402 revolutions/minute (rpm) and by a belt drives the compressor at 3600 rpm. It is found that the vertical force fed to the support is excessive. Choose four equal springs to provide a force transmissibility not exceeding 4%.

Need help. Please solve this and clearly state how you got your numbers and what formulas you used to solve it. Please make sure you find all the 6 unknows please. Knowing the beta equals 30° and the solid plate weigh 100 kg. What is the cable tension T and the reaction forces at the two bearings? Assume bearing A is a thrust bearing but bearing B is notplease solve for the X component at bearing B. Again please also make you find all the 6 unknows please. And clearly indicate which is which. And please label and make sure it put units
