A loading condition is shown below. Using Castigliano's theorem and by applying a fictitious force Q with a magnitude of 0 at point C, determine: a) The horizontal displacement of point C. a) The vertical displacement of point C.

Question 1 The generator shown is being lifted by a (91 0001)9 G2(250 lb) crane, and the moving team needs to know the center of gravity so that the generator does not tip during transport. The weights of multiple components of the generator (91 007)'ɔ are shown. a) Find the distance from A to the center of gravity, x. x = 4. 28ft b) Determine the support reactions at YE point A and point B. A, = 830 Ib, B, = 620 Ib

Pushing a Block and a Wedge 0 points possible (ungraded) In the following problem, you are asked to: i) Define the system and the environment: Identify which objects - the environment - interact with the object of interest - the system. Justify your choice of system: would a different choice also work? If not, why not? If so, why is the choice you made better? ii) Describe the interactions and the resulting forces: Identify the forces exerted on the object of interest by the other objects. iii) Draw the free body diagram of the object: Make sure that each force arrow is labeled with two subscripts - who is exerting the force and on whom is the force being exerted. The length of the arrows should represent qualitatively the magnitude of the force. a) c) M m 0 a F M m 0 A block of mass m rests on a frictionless wedge which has a mass M and whose surface makes an angle to the horizontal as Calculator

1.2 m 1.4 m Im 30° 2 m A) Draw a Free Body Diagram of the 75 kg hatch. Make an assumption to keep the problem statically determinate. B) Compute the tension in the rope. C) Compute the reactions at A and B.

A uniform drawbridge must be held at a 38.5 ∘ angle above the horizontal to allow ships to pass underneath. The drawbridge weighs 45000 N, is 13.0 m long, and pivots about a hinge at its lower end. A cable is connected 3.80 m from the hinge, as measured along the bridge, and pulls horizontally on the bridge to hold it in place. a) What is the tension in the cable? b) Find the magnitude of the force the hinge exerts on the bridge. Find the direction of the force the hinge exerts on the bridge. c) If the cable suddenly breaks, what is the initial angular acceleration of the bridge?
