CDEFGH is plate with a circular hole in it and has a unit weight p = 2 kN/m². If the initial length of the spring is 1m, find the stretched length of the spring attached at C to the given system. The stiffness of the spring id k=50 kN/m.

Please assist me in drawing the free body diagram. I'm not sure what happened at C for member ABC.

A woman is holding a 3.7-kg sphere in her hand with the entire arm held horizontally as shown in the figure. A tensile force in the deltoid muscle prevents the arm from rotating about the shoulder joint O; this force acts at the 21° angle shown. Determine the x- component of the force reaction at the shoulder joint O. The mass of the upper arm is my = 1.9 kg, the mass of the lower arm is m₁ = 1.1 kg, and the mass of the hand is my = 0.4 kg; all the corresponding weights act at the locations shown in the figure. Calculate your answer with one decimal figure accuracy. g = 9.81 m/s². Deltoid muscle FD 21° 125 mm 130 mm WU 412 mm- y 1 I L- 635 mm YW₂ Ws WH

A two degrees of freedom mass spring system is fixed at one end, where independent masses can move only in the vertical direction. Considering the system as finite elements, determine the vertical displacement for each mass. Also draw the free body diagram of this system. Use 'X' KN/m as the stiffness value for all the springs and 'Y' Kg as the value for all masses. Where, 'X'= (63) 'Y'= (93)

The right end of a horizontal beam of mass 4kg and length 3.3m is fixed to a wall by a hinge. The left end is held by a rope making an angle of 25.2 degrees with the horizontal. At the left end, a block of mass 9.3 kg is suspended.Determine the modulus and orientation of the force exerted by the hinge on the beam. Express with an x+ axis which is to the right.
