- A bored student builds a levitating lantern using objects they 3D printed in the Fischer Engineering Design Center. The student connects the blue and green pieces with two strings at points A and B, as shown below. If the blue (top) object weighs 181 g and the tension in string A is 3.2 N, what is the distance from the left side of the object to its center of mass in cm? Assume the system is in static equilibrium.I need your help expert. The system shown below is in equilibrium. Spring 3 is known to have a change in length of 10 cm. The magnitude of the compressive force in Spring 2 is 15% more than the magnitude of force P, while the magnitude of the compressive force in Bar 1 is 100 N less than that in Spring 2. If the spring constants of Springs 2 and 3 are 625 and 1200 N/m, respectively, determine the following: a. magnitude of forces P (in N) and F (in N) b. tension (in N) in cable ABC c. mass (in kg) of Block A d. compressive force in Bar 1 e. change in length (in cm) of Spring 2 Draw the complete FBD’s of Block A, Hook C and Pulley E.

- Select the correct statements regarding the equilibrium of coplanar forces. (Select 3) For forces acting in the same direction and having the same line of action, the resultant force is the arithmetic sum of the separate forces If forces applied on the object do not share the same line, then the object is not possible to reach an equilibrium state Conditions for equilibrium require that the sum of all moments from external forces is zero Conditions for equilibrium require that the sum of all external forces acting on the body is zeroQUESTION 4 In the structure below, member AB is attached to the wall with a fixed support at A and is attached to member BC with a fixed support at B.
