An automatic production machine requires a com contact with a cam that rotates at a speeds up to 1800 rpm. When installed, the spring force is to vary between 150 and 600 N while the spring height varies over a rang available supply of 4.5 mm diameter shot peened wire to be used. Clash allowance (difference in spring length between maximum load and spring solid positions) is to be 2.5 pression coil spring to keep a follower in Determine appropriate...

4. A compression spring is needed to fit over a 12mm diameter rod. To allow for some clearance, the inside diameter of the spring is to be 15mm. To ensure a reasonable coil, use a spring index of 8. The spring is to be used in a machine by compressing it from a free length of 125mm through a stroke of 75 mm to its solid length. The spring should...

Design an infinite-life helical coil extension spring with full end loops and generous loop-bend radii for a minimum load of 9 lbf and a maximum load of 18 lbf, with an accompanying stretch of in. The spring is for food-service equipment and must be stainless steel. The outside diameter of the coil cannot exceed 1 in, and the free length cannot exceed 21 in. Using a fatigue design factor of nf 2, complete the design. Use the Gerber criterion with...

1. An existing helical-coil compression spring is wound from unpeened music wire with a diameter of d= 0.105". The mean diameter of the spring is D- 0.80" as shown. The applied load fluctuates between 0 and 25lb. A design life of 10 cycles is desired. We also know that 0.577Su for this music wire. Determine the existing factor of safety for this spring n2.0 (Hint: check both fatigue and yielding) D = 0.80 in
A compression spring is needed to fit within a 1-in diameter hole. To allow for some clearance, the outside diameter of the spring is to be no larger than 0.9 in. To ensure a reasonable coil, use a s...
A compression spring is needed to fit within a 1-in diameter hole. To allow for some clearance, the outside diameter of the spring is to be no larger than 0.9 in. To ensure a reasonable coil, use a spring index of 8. The spring is to be used in a machine by compressing it from a free length of 2 in to a solid length of 0.6667 in. The spring should have squared ends, and should be unpeened, and is...
