1. Old MacDonald had a farm, and on that farm he had a gate (see below). The gate is 3m wide and 1.8m high, with hinges attached to the top and bottom. The guy wire makes an angle of 30° with the top of the gate and is tightened by a turn buckle to a tension of 200 N. The mass of the gate is 32kg. 30.0° 1.80 m 3.00 m (a) Determine the horizontal force exerted on the gate...

#4 please
A uniform sheet of metal in the shape of a hemisphere of radius 1 m is used as a sign. The hemisphere has a mass of 200 kg and is suspended by two vertical wires attached to points along its horizontal diameter. One wire is attached to the left end of the diameter and the other is attached to a point three-quarters of the way to the other end. What is the tension in each wire? A ladder...

A crane is made from a uniform rigid boom of length L = 30m and weight w = 400N. The boom is sup- ported by a frictionless hinge at its lower end. Its upper end is attached to a support cable which is fas- tened behind the boom at the same horizontal level as the hinge. Adjusting the length of the support / cable adjusts the angle of the boom. In a particu- 7/TTI IN lar application, the crane is...

Question 1: Hanging block (12 points) A horizontal rod of mass M and length L is attached to a hinge and supported at its end by a massless wire oriented at an angle o relative to the rod. A block of mass 4M is connected to the rod at a distance L/3 from the hinge. The system is in static equilibrium. (a) [2 points) Question: Draw the free-body-diagram, i.e., all external forces acting on the block-rod system. Answer: (b) [7...

2) See Figure 2. A 35 kg sign is suspended from the end of a uniform horizontal beam that has a mass of 25 kg and a length of 3.0 m. The beam is attached to a wall by a hinge. A cable with negligible mass is attached to the end of the beam just above the sign and extends to the wall, forming an angle of 30° with the beam. cable beam Physics is Phun Figure 2 a) Sketch...

(III) A uniform rod AB of length 5.0 m and mass M = 3.8 kg is hinged at A and held in equilibrium by a light cord, as shown in Fig. 9-67. A load W = 22 N hangs from the rod at a distance d so that the tension in the cord is 85 N. (a) Draw a free-body diagram for the rod. (b) Determine the vertical and horizontal forces on the rod exerted by the hinge. (c) Determine...

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 whether...

" A mass hanging from a vertical spring is somewhat more complicated than a mass attached to a horizontal spring because the gravitational force acts along the direction of motion. Therefore, the restoring force of the oscillations is not provided by the spring force alone, but by the net force resulting from both the spring force and the gravitational force. Ultimately, however, the physical quantities of motion...

1. The block shown in the figure has a mass of 612 Kg. The static coefficient of friction between the block and the supporting surface is 0.33 while the kinetic coefficient of friction is 0.26. Ignore the size of the block. Force P is parallel to the incline while the 1000N force is vertical. a) If P = 2000 N, the shown block is (circle the correct answer) (5 points) a) in equilibrium b) moving up the incline c) is...
