Compression springs are the most common spring configuration that product manufacturer's turn to
when enhanced product functionality is required. You are required to design a compression spring
that is made of oil-tempered wire of 4-mm diameter with a spring index of C=10. The spring will
operate inside a pipe, so buckling is not a problem and select the ends to be plain. The free length of
the spring should be 80 mm. A force of 50 N should deflect the spring 15 mm.
a) Calculate the spring rate and the solid length.
b) Calculate the total number of coils needed.
c) Calculate the minimum pipe diameter for the spring to operate in.
d) Calculate a static factor of safety based on the yielding of the spring if it is compressed
to its solid length.
basically we’re designing a machine that has rollers to flattened and rotating shaft to roll a strip of dried leaves into a bundle. Now we were advised to provide calculations with the relevant engineering parameters including the sizing of gears, belt and pulley, the torque requirement of each machine element and the power rating of the motor.
The entire machine is powered by a stepper motor connected with a timing belt and pulley for power transmission. and gears that will rotate the shaft.
Can you give us the flow of calculations from the rollers, the rotating shaft, up to sizing pf belt and pulley and gear ratios, with the last step as finding the power requirement (in hp) of the entire machine?
Give an example of the Resistance Factor?

- Project 4: Pipe lagging is an insulation fitted around pipes to maintain energy loss at minimum and prevent any freezing or bursting. Your part in the HTU thermodynamics and heat transfer lab is to conduct an experiment to explore the heat losses that would occur in both lagged and unlagged hot water pipe. The required tools and main apparatus are shown in Figure.4 and general schematic is shown in Fugure.5. Figure.1, shows the pump for providing running the cycle, thermocouple for measuring the temperature and the pipe coil. Your lab instructor asked you to perform the following tasks: • Fit the lagging around the pipe • Connect the pump to inlet of coil • Measure the hot water terampere at the inlet (make sure the temperature reaches its steady state before measuring it) • Operate the cycle by turn on the pump • Measure the cold water terampere at the outlet in steady state. • Repeat the previous step with unlagged pipe • Search for an appropriate video where a test to measure the…arrow_forwardTOPIC: Machine Design Multiple choice Note: Please also provide a solution that proves the correct answer.arrow_forwardPls. refer to the answer keys so that I will know if my solution is wrongarrow_forward
- When lifting weights, it turns out the amount of force you need to lift them doesn't necessarily match the dumbbell's weight — in other words, if an object weighs 100 N, the amount of force you actually need to apply is probably not 100 N. Observe the diagram below: You can think of the bones in your arms as rods that rotate about an axis of rotation (your elbow) depending on the magnitude, direction and position of the forces being applied. So in order for your arm to lift the weight, the torque exerted by the bicep should be greater than or equal to the torques being applied by the bones' center of mass and the weight your hand is holding. Notice how the bicep is connected to the arm bone (the radius) at a certain distance from the joint, and applies an upwards tension force (as the bicep contracts in order to lift objects). Show how the magnitude of the tension force exerted by the biceps muscle can differ greatly from the magnitude of the weight.arrow_forwardneed correct and urgentarrow_forwardQ2/ semiconductor at T, has conductivity of 2.5 x 106 s/m. number of electrons of 3x 103 Numbers of holes 3x 103 ,charge of 1.602 x 10 -19 c, and at T2 has conductivity of 3.6 x 10 s/m , number of electrons of 4.5x 1014 , Numbers of holes 2x 102 ,charge of 1.602 x 10-19 c.

- 118... Medical The bones of the forearm (radius and alna) are hinged to the humerus at the elbow (Figure 8-65). The biceps muscle connects to the bones of the forearm about 2 cm beyond the joint. Assume the forearm has a mass of 2 kg and a length of 0.4 m. When the humerus and the biceps are nearly vertical and the forearm is horizontal, if a person wishes to hold an object of mass M so that her fore- arm remains motionless, what is the relationship between the force exerted by the biceps muscle and the mass of the object? Example 8-17arrow_forwardQUESTION 1 Spring is an elastic body whose function is to store energy when deflected by force and return equivalent amount of energy on being released. For the purpose of saving energy and improving the performance of vibration isolation system, advanced springs with light weight effect and high performance have been widely used for today's automobiles and mechanical systems. A helical spring is a reliable elastic component usually used in the suspension of automobile to absorb shocks caused due to irregularities of the road surface and to provide a comfortable ride to passengers. A static music wire helical compression spring is needed to support a 90 N load after being compressed 50 mm. The solid height of the spring cannot exceed 35 mm. The free length must not exceed 95 mm. The static factor of safety must be calculated and the value must be equal or exceed 1.15. For the robust linearity, use a fractional overturn to closure & of 0.15. The spring must operate in a 30 mm diameter…arrow_forwardUse appropriate diagram and sketches. When the cold junction of a thermocouple thermometer is at 0° C and the hot junction at 100°C the millivoltmeter shows a deflection of 4.2 mV towards the left. The cold junction is now put in an unknown temperature while maintaining the hot junction at 100°C. The millivoltmeter now shows a deflection of 5.2 mV towards the right.
