The drawing shows a top view of a hockey puck as it slides across frictionless ice. Three forces act on the puck, and it is in equilibrium. The force F is applied at the center and has a magnitude of 31 N. The force F1 is applied at the top edge, and F2 is applied half way between the center and the bottom edge. Find the magnitude of F1 and F2.

The drawing shows the top view of two doors. The doors are uniform and identical. Door A rotates about an axis through its left edge, and door B rotates about an axis through its center. The same force is applied perpendicular to each door at its right edge, and the force remains perpendicular as the door turns. No other force affects the rotation of either door. Starting from rest, door A rotates through a certain angle in 3.05 s. How...

The drawing shows a 26.9-kg crate that is initially at rest.
Note that the view is one looking down on the top of the crate. Two
forces,
and , are applied to the crate, and it begins to move. The coefficient
of kinetic friction between the crate and the floor is k = 0.307. Determine the (a) magnitude
and (b) direction (relative to the x-axis) of the acceleration of the crate.

the shoulder joint, which is represented by point O. The
shoulder pushes down and to the right on the humerus bone of the
arm with a force

Figure Q5(a) shows a plane truss supported by a horizontal spring at the top node. The truss members are of a solid circular cross section having a diameter of 20 mm and an elastic modulus (E) of 80 GPa (10° N/m2). The spring has a stiffness constant of k-2000 kN/m. A point load of 15 kN is applied at the top node. The direction of the load is indicated in the figure. The code numbers for elements, nodes, DOFS, and...
