Problem 2 A capacitive force sensor is made as shown in Figure P2. The three plates are identical, each w=10 mm wide and L=20 mm long. The two outer plates are fixed, whereas the center plate is suspended on a spring so that at zero force the three plates are aligned. Between the plates there is a separation sheet made of Teflon with relative permittivity of 2.25 and thickness d=0.1 mm (one on each side of the center plate). a) If the spring has a constant of 100 N/m, find the transfer function of the sensor and its sensitivity. b) What is the maximum span of the sensor? boo0

Problem 7. We have a line of two equal masses m connected by three springs with spring constants c₁ = 1, c₂ = 1, and c3 = S. Spring 1 is fixed at the top and spring 3 at the bottom, so xo = x3 = 0. (a) Find the stiffness matrix K in the equation Kx = f for the mass displacements. (b) Solve for the displacements x₁ and x2. (c) If the third spring constant S becomes very large or very small (S→∞ and S→ 0) what are the limiting values of the displacements x₁ and .x₂? (d) If the third spring constant S becomes very large or very small (S→∞ and S→ 0) what are the limiting values of the spring forces y1, y2, and y3? 91 www m 3-WW www C₁ X₁ "Xo = 0 C2₂ X2 C3 X3 = 0
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

The frame ABC is supported by the 2 mm diameter, A-36 steel cable DB and by a pin support at A. You are required to: a Calculate all the internal forces acting at the cross section b-b and in cable BD. b Calculate the orientation of the plane and the magnitude of the maximum in- plane shear stress at point F, on section b-b, and represent this condition using a stress element. с Determine the factor of safety (F.S.) of the cable BD for this loading based on the maximum-distortion energy theory (von Mises).

The length of the spring AB before it is deformed is 3m. What should be the value of the weight to be suspended from point D in order to maintain balance. (I am trying so hard for this problem but I couldn't handle it . Please help me .)
Each situation in Figure 8.26 shows a uniform beam, of weight 50N and length 4 m, held horizontally in equilibrium by two light inextensible strings. Find the tension in each string. hi can you please explain it fully? please see the image attached for the diagram if you use * can you explain what it means. thank you
