I need your help expert. The system shown below is in equilibrium. Spring 3 is known to have a change in length of 10 cm. The magnitude of the compressive force in Spring 2 is 15% more than the magnitude of force P, while the magnitude of the compressive force in Bar 1 is 100 N less than that in Spring 2. If the spring constants of Springs 2 and 3 are 625 and 1200 N/m, respectively, determine the following: a. magnitude of forces P (in N) and F (in N) b. tension (in N) in cable ABC c. mass (in kg) of Block A d. compressive force in Bar 1 e. change in length (in cm) of Spring 2 Draw the complete FBD’s of Block A, Hook C and Pulley E. (Note: Below are the final answers, kindly match your answer on this. Thank you) Answer: P = 131.2831 N, F = 87.1569 N, TABC = 110.7024 N, mA = 15.6338 kg, F1 = 50.9756 N, s2 = 24.1561 cm

1. Three forces act on particle A located at the origin of an x-y coordinate system. Force B acts at 140o from the positive x-axis, and force C acts at 15o from the positive x-axis. The weight acts down with a magnitude of W = 100 kN. Use the equations of equilibrium to determine the magnitudes of B and C such that particle A is in equilibrium. For problems 2-5, consider the following scenario. Equilibrium of a particle: ΣF=0 ∴ ΣFx=0 and ΣFy=0. Dimensions are: h = 2.5 ft, d1 = 4.75 ft, and d2 = 3 ft.

Problem 1: Recall the two-mass system from a previous problem set, in which you deter- mined the (stable) equilibrium point of the system. (a) Let y be the distance of the bead from the ceiling. From the earlier problem, rewrite U(0) so that the potential energy is a function of this variable y, instead of 0. Also, given the expression for the equilibrium angle, find the equilibrium position yo for this system. (b) Expand U(y) in a Taylor series around yo to show that for small oscillations, U(y) can be written in the Hooke's Law form ky², and determine the "effective spring constant" k. (c) Write the total kinetic energy T of the system as a function of y. Compare your kinetic and potential energy for this system to the energy expressions in the SHO, and determine this system's angular frequency for small oscillations. M b Ꮎ m
