Consider the system shown in FIGURE P3-44 of the textbook. The designer has made several changes to the system. These changes are: • the load of 6 kN/m has been changed to 11 kN/m, • the central length of 2 m has been changed to 4 m o this means the load is applied over the beam from 1 m to the right of point 'A' T0 point 'C'. What is the magnitude of the resultant of the distributed load? 5 kN 55 kN 0.513 kN 93.6 kN 11 kN 12.1 kN 91.4 kN O kN

The forces acting on the arm of an athlete doing shoulder exercises are shown in the figure. The athlete holds his arm at an angle of β = 30° with the horizontal axis . Point O represents the axis of rotation in the shoulder joint, point A represents the connection point of the deltoid muscle to the humerus, point B represents the center of gravity of the arm, and point C represents the application point of the force acting on the hand. The distances between the rotation axis (O point) of the shoulder joint and the points A, B and C are a=22 cm , b =33 cm and c= 60 cm , respectively . A force of F= 120 N, which makes an angle of γ=30° with the vertical from the point C, acts on the athlete's hand . Weight of the athlete's armW= 80 N.

The forces acting on the arm of an athlete doing shoulder exercises are shown in the figure. The athlete holds his arm at an angle of β=15° with the horizontal axis. Point O represents the axis of rotation in the shoulder joint, point A represents the connection point of the deltoid muscle to the humerus, point B represents the center of gravity of the arm, and point C represents the application point of the force acting on the hand. The distances between the rotation axis (O point) of the shoulder joint and the points A, B and C are a=20 cm, b =33 cm and c= 65 cm, respectively. The athlete's hand is exerted by a force of F= 150 N, which makes an angle of γ=30° with the vertical from the point C. The weight of the athlete's arm is W= 100 N. The direction of application of the Fm muscle force makes an angle of α=25° with the longitudinal axis of the arm. According to this; a) Calculate the FM muscle strength. b) Calculate the angle θ of the FJ joint reaction force with the horizontal.…

1. Three cubes of side l0, 2l0, and 3l0, are placed next to another (in contact) with their centers along a straight line and the l = 2l0 cube is in the middle (see Figure below).a) If the cubes are made of the same uniform material, find along this line the position of the center of mass of the system.b) We now replace the cube in the middle (l = 2l0) by another cube of the same volume but made of a different uniform material. What would be the mass density  of this cube compared to the mass density 0 of the initial cube if we want to locate the center of mass of the new system at the interface between the cube in the middle (l = 2l0) and the right-hand cube (l = 3l0)?
