please show all work 16) In the figure, a 10.0-m long bar is attached by a frictionless hinge to a wall and held horizontal by a rope that makes an angle 0 of 53° with the bar. The bar is uniform and weighs 39.9 N. How far from the hinge should a 10.0-kg mass be suspend ed for the tension T in the rope to be 125 N? 10 kg 10 m ctin
Consider the free-body diagram of a person holding a ball with their arm extended horizontally, as shown below on the left. The ball weighs WB 30 N, and is held at a distance d0.35 m from the elbow (E). The lower arm weighs WA 10N, with the center of mass distance 1- 0.15 m away from E. The biceps muscle applies a vertical upward force B to the lower arm at distance s - 0.03 m from E. a) What...

1. (20 Marks) An object has an L-shape and can be treated as 2 beams fixed together at right angle. Beam 1 (B) has a weight wi = 180 N and a length Li-2.00 m and Beam 2 (B) has a weight w2 90.0 N and a length L2- 1.00 m. This object is hinged by its corner O to the ground via a hinge that allows it to rotate clockwise counter clockwise, when possible. B2 rope B2 0 Figure...
include free body diagram . [18 pts] A uniform long slender bar of mass m 6.8 kg and length0.9 m is attached at one of its ends (A) to a horizontal rope while its other end (B) slides without friction on the floor. For the instant when the bar is released from rest in the configuration shown (where θ 45 degrees): (a) Develop expressions for a and ay, the accelerations of the bar's centre of mass in the along with...
nutaud 4) Read the following and revise your free body diagram as necessary. A common confusion when drawing extended free body diagrams is how to draw the force of gravity. For a static equilibrium situation like this, you should draw a single arrow to represent the force of gravity on an extended object. The tail of this vector is placed at the center of mass of the object. It is good practice to pause at this point and think about...

Please solve problem 2 showing all steps and free body diagrams. 6.10 Problems Problem 6.1. A man is performing dumbbell kickbacks to strengthen his triceps (Fig. P.6.1). He weighs 55 kg. His forearm and his hand together constitute 2.5% of his body weight. The length of his forearm is 26 cm. The lever arm of the triceps with respect to the center of rotation of el- bow is 2.4 cm. The weight he carries is equal to 5 kg. Assuming...

What is the MAXIMUM weight ww that can be used to hold this crate stationary on the ramp? Include free-body diagrams of the two masses. Now assume that the weight w=3000N. What is the acceleration of the crate? Find the speed of the masses after the weight w=3000N has dropped a distance of 1.6m after being released from rest. Find this speed two ways: using kinetmatics and the acceleration derived in the previous subquestion, and using energy considerations. A 2000-N...
