Required information A helical compression spring is wound using music wire of diameter, d, 2.16 mm. The spring has an outside diameter, OD, of 27 mm with plain ground ends and 14 coils. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. What is the force needed to compress this spring to closure assuming that the spring will reach its shear strength at its solid length? The force needed to compress this spring to closure is |N.

View In: English v In the below arrangement, all the string and pulleys are massless and the inclined plane is frictionless. At t 0, spring is unstretched and a constant force F = mg starts to act. Find the maximum extension in the spring. (Assume incline to be sufficiently long). Question 11 F=mg Options 8mg 1. O k 4 mg 2. O 5 k 8 mg 3. O 15 k 8mg 4. O 3k

6. It is desired to design a valve spring of I.C. engine for the following details: (a) Spring load when valve is closed 80 N (b) Spring load when valve is open = 100 N (c) Space constraints for the fitment of spring are : Inside guide bush diameter = 24 mm Outside recess diameter= 36 mm (d) Valve lift 5 mm (e) Spring stcel has the following properties: Maximum permissible shear stress = 350 MPa Modulus of rigidity 84 kN/mm? ried: 1 Wire diameter; 2. Spring index; 3. Total number of coils; 4. Solid length of sprine: 5. Free

Problem. Consider the following problem. Find the displacement of node 4. Assume F2=200 N, F3=300 N, F4=400 N and Kı= 100, K2= 200, and K3= 300 N/mm. F. 3 2 3 4 Note: The stiffness matrix of individual springs should be first written, then the equilibrium equations at each node should be written, expanded in terms of nodal displacement, and used to perform the assembly of the global stiffness matrix of the problem. Then, the appropriate boundary conditions should be applied and the nodal displacement vector should be found. Every step should be shown; missing any step would result in point deduction even if the final answer is correct.

A helical compression spring is subjected to a maximum force, Fmax of 1250 N. The deflection of the spring corresponding to the maximum force should be approximately 30 mm. The spring index is 6. The allowable shear stress is 350 MPa and the modulus of rigidity is 81 370 N/mm². Design the helical spring by calculating the wire diameter, mean coil diameter, number of active coils and the total number of coils. State all assumptions and decisions in your design.

Hi, I have been given this pin-jointed frame analysis to solve (see pictures of the structure attached). Can you help me? The Figure 2 attached is a simplified structure to undertake a structural analysis on a concept design for a low cost stroller/buggy for children. The buggy consists of a number of metal sections that are pin-jointed together. The buggy is designed to accommodate a child of mass no more than 20 kg, sat on the seat which is supported at four points (Fc) on the frame of the buggy.  Assume that the weight of the child is equally distributed across all of the points  indicated on Figure 2 as Fc. Assume that there are no additional forces applied to the handle of the buggy, that the buggy is static (stationary) and that the buggy, and the elements of the frame have no mass. At points A and G, there are roll supports. At Points B, F and D there are the pin supports. I am required to determine the following: 1) Draw a free-body diagram of the structure 2) Simplify the Free…
