igure 2. Assume that the rod is massless, perfectly rigid, and pivoted at point P. When the rod is perfectly horizontal, the angle 0 = 0, the displacement y 0, and the springs are in neither tension nor compression. Gravity acts on the system (e.g. on mass M). We assume that y is a small displacement. A mass M is attached at the end of the rod.

mb: L d- ms A horizontal L=1.2 m long mb=12 kg uniform bar is hinged on the left end and pulled at the right end by a cable. The cable makes 31° angle with horizontal. A 18 kg store sign is suspended below the bar at d=0.18 m from the right end. Find the magnitude of vertical hinge force.
Calculate the reaction forces on the bearing near the pulley and bearing at the far end of the shaft. Include a free body diagram and coordinates. Given the shaft length is 1 meter= Mass=40Kg Static load = 8600N Dynamic (running load) = 8400N Some hints:1. This solution will require you to draw known forces and find unknown reactions in 2perpendicular planes and then add the horizontal and vertical reaction forces asvectors to find the reaction force (hypotenuse).2. Bearings are usually mounted as near as possible to the ends of the shaft withoutfouling the other machine elements. The bearing at the far shaft end can be mountedat the 1 meter point. The bearing at the pulley end should allow clearance to assemblethe pulley.3. Bearing reaction forces are typically simplified as a single point load through thebearing centre.

OP •C h W The man in the diagram is trying to move a large box by pushing on it with a force, P. The box weighs 300 N and its centre of gravity is located in the centre of the box (point C). Given: a = 1.8 m b = 0.8 m h= 0.9 m What is the minimum force that will cause the box to tip? Please include the unit ("N") within your answer and round to 3 significant figures (e.g. if the calculated answer was 55.562 Newtons please input: 55.6 N). Answer: What is the minimum coefficient of static friction that will permit tipping to occur? Please do not include the unit s (as there are none) within your answer and round to 3 significant figures (e.g. if the calculated answer was 55.562 please input: 55.6). Answer:
Consider the double mass spring system shown in the figure below. www x₁ = 197} The positions X₁ and x₂ of the two masses are given by the system [90-1* m2 x2 = = 197₂ -(k₁ + K₂) k2 X1 ][*] Xx2 k₂ -(k₂ + k3) + F. Let m₁ = 1, m₂ = 1, k₁ F₁ = 9 cos(6t) on the first mass and a force F2 = 0 on the second and the masses start from rest ( x₁ (0) = x₂(0) = 0 ) and at their equilibrium positions ( x₁ (0) = x₂(0) = 0 ), find the resulting motion of the system. = 1, k₂ = 4 and k3 = 1.
