Question

1. The figure shows a uniform rod of mass m = 4.00 kg held in
static equilibrium by a frictionless pivot, P, that is fixed to the
horizontal ground, and a cable. A load of mass M = 12.0 kg
hangs from the end of the rod. The rod is uniform and its length
is L = 2.00 m. The angle 0 is 42.0°.
Cable
M
Calculate the magnitude and direction of the force that the pivot exerts on the rod.

F y mg f.Y Frxe f,x Axis The ladder in the picture has a mass of 32 kilograms and a length 3.2 meters. What is the normal force pushing the ladder up from the floor? FN = Assume that the ladder's weight is evenly distributed, so it can be treated as a single force through the middle. If the ladder is at a 60° angle from the ground, what is the torque exerted by the weight (using the floor as the pivot point)?
The uniform 19.0 kg beam below is 6.4 m long and is perfectly balanced about a point 1.4 m from the left end. What is the mass of the block? (Hint: when calculating the torque due to the weight of the beam, consider all of its mass to be located at its center of mass.)
‘The uniform brass bar AB has a rectangular cross section and is supported by pins and brackets as shown. Each end of the bar can rotate freely about a horizontal axis through the pin, but rotation about a vertical axis is prevented by the brackets.

(b) Determine the factor of safety if P =1.8 kips , L= 7 ft. d =1.5in. and E= 20 X 10 psi
A bar 1m in length has a negligible mass and it is placed on a pivot point at the 0.55 m mark. A 2.3 kg mass hung at the 0 m mark and a 1.5 kg mass hung at the 1.0 m mark.

Immediately after release, the magnitude of the SUMMATION OF TORQUE on the bar about the pivot point is most nearly A 16 N•m В 2.0 N•m C) 6 N•m 8.0 N•m E 19 N•m
Two identical heavy spheres are seperated by distance 10 times their radius. Will an object placed at the mid point of the line joining their centres be in a stable equilibrium or unstable equilibrium ? Give reason for your answer.
Two uniform planks, each of mass m = 7.45 kg and length L = 2.51 m, are connected by a hinge at the top and by a chain of negligible mass attached at their centers, as shown in the figure. The assembly will stand upright, in the shape of an A, on a frictionless surface without collapsing. If the chain has the length 0.81 m, find each of the following: a) the absolute value of the tension in the chain, b) the absolute magnitude of the force on the hinge of each p lank
In an emergency situation, a person with a broken forearm ties a strap from his hand to clip on his shoulder as in the figure below. His 1.60-kg forearm remains in a horizontal position and the strap makes an angle of ? = 47.0° with the horizontal. Assume the forearm is uniform, has a length of ℓ = 0.332 m, assume the biceps muscle is relaxed, and ignore the mass and length of the hand. A person with a broken left forearm faces out of the page. His left forearm is approximately horizontal, and a strap extends from a clip on his right shoulder to a position on his left arm that is a distance ℓ from the elbow. The strap is at an angle ? above the forearm. A force vector R acts up and to the right on the left forearm at a location just left of the elbow. (a) Find the tension in the strap. N(b) Find the components of the reaction force exerted by the humerus on the forearm. (Assume the positive x-direction is to the right and the positive y-direction is upward.) Rx = N Ry= N
