Problem 10. If two forces are acting on a beam as shown, and FI -10 N, and F2 - 15 N, what is the force of F3n if the beam is not to move? Problem 11. Four people are pushing on a door as shown on the figure, and the forces given are; FI - 10 N, F3 - 15 N, F4 is 35 N, what is the force of F2 if the door is not moving? Problem 12. If...
Class Activity Consider an unreinforced concrete beam cross section with the dimensions (in inches) shown in the figure. The comcrete is sormal-weight with 6000 psi145Ib/f The section is subjected to a positive beading moment of 500 kip-ft about its horizontal axis causing compression and tension on the faces as shown. Assume the section remains elastic under this moment 15 Tension 20 Determine centroid of the section from the compression face. Answer: c-7.622 in (A) Determine moment of inertia of the...
Determine the moment of force about the point where a
bracket is attached to a wall. The bracket is shown in figure. It
extends 10 inches out from the wall and 5 inches up. A force of 35
lbf is applied to the bracket at an angle of 550 from the vertical.
The answer should be inft-lbf, so you need to do some conversions
of units. (Moment must be in foot-poundforce)

mass weighing W pounds stretches a spring 7 foot and stretches a different spring foot. The two springs are attached in series and the mass is then attached to the double spring as shown in the figure below. (a) A rigid suppont that the motion is free and that there is no damping force present. Determine the equation of motion if the mass is initially released at a point 1 foot below the equlbrium postion with a downward velocity of...
