A swinging door that weighs w=400.0N is supported byhinges A and B so that the door can swing about a vertical'axis passing through the hinges (as shown in below figure).The door has a width of b=1.00m and the door slab has auniform mass density. The hinges are placed symmetricallyat the door's edge in such a way that the door's weight isevenly distributed between them. The hinges are separatedby distance a=2.00m. Find the forces on the hinges whenthe door rests half-open. Draw Free body diagram also.[5 marks][CLO 1.2]Moolbరa2.0 mB1.0 m

Answer in this format. Sketch: Given: Required: Solution: (Please answer in detailed (step by step). Indicate labels on what you are doing/performing, for example what formula is used) An electrical worker stands in the bucket that hangs from a pin at end D of the boom of the cherry picker in Fig. 1. The worker and bucket together weigh a total of 300 lb. Between A and C the boom weighs 1.1 Įb/in., and between C and D it weighs 0.8 Jb/in. Assume that AC and CD are uniform beams. Determine the normal force, the transverse shear force, and the bending moment that act at cross section E, midway between A and B.

Part 1 Use the graphical method to construct the shear-force and bending-moment diagrams for the beam shown. Let a=4.0 ft, b-9.0 ft, c-5.0 ft.d-4.0 ft. w- 10.5 kips/ft and P-117 kips. Construct the shear-force and bending-moment diagrams on paper and use the results to answer the questions in the subsequent parts of this GO exercise. A D For this loading, calculate the reaction forces A, and Ey acting on the beam. Positive values for the reactions are indicated by the directions of the red arrows shown on the free-body diagram below. (Note: Since Ax = 0, it has been omitted from the free-body diagram.) Answers: Ay= D d 2 kips, Ey E kips Part 2 Determine the shear force acting at each of the following locations: (a)x=0+ ft (l.e., just to the right of support.A) (b)x=4,0 ft (c) x-13.0 ft (d) x-18.0-ft (le, just to the left of D) (e)x= 18.0+ ft (l.e., just to the right of D) (f)x=22.0-ft (ie, just to the left of support E) When entering your answers, use the shear force sign convention.…
Free body diagram Draw the free body diagram (FBD) for this system. To draw the free body diagram, we assume that the bar is displaced a small amount in the positive direction of 0. Important: For the free body diagram, the forces also need to be labelled! You can draw the forces by clicking the application point (letters) and dragging or using the drop down with the 'draw' button. If you drew them by clicking and dragging, click the force vector to label it from the dropdown menu above. If the label on the force doesn't appear on the diagram, you haven't quite done it right and the question will keep getting graded as incorrect even if you have the correct arrows. Fs k2 Fry Fg k1 Frx Equation of Motion Since the bar undergoes rotational motion, Newton's second law is written by writing a sum of moments around the pivot point (sum of moments cause rotational motion). Positive moments are those that are in the direction that tend to move things in what is defined as the positive…

3. In a science fiction story about space exploration an expedition to Mars was described. The space ship landed in a rocky valley and the astronauts promptly prepared their vehicle for a trip on the planet's surface. This special vehicle was designed with big inflated tires. On the very first steep slope the vehicle tipped over. They did have small steel balls onboard to increase traction. They thought of suspending a bunch of them beneath the vehicle to lower its center of gravity, but that would decrease the clearance and cause the weights to strike rocks and the ground more often How could it be done?
QUESTION 8 Find the force generated by the deltoid (right arm) if: His arm length (d) is: 0.84 m The COG of the arm is 37% away from the proximal end His arm weighs 7.9N The weight weighs 126 N The angle of the arm from vertical (@): = 90 degrees The deltoid insertion is 0.17 m from proximal end The line of pull for the deltoid is: 11 degrees Round to the nearest whole # and assume the final answer is positive. Leave no space between answer and units.
1. You are tasked to design a shaft for power transmission through a belt and pully at its right side. The shaft is supported by a thrust bearing at A and a journal bearing at B. a) Determine the support forces the bearings have to "bear". (In machine design, this step is necessary for selecting the correct bearings from the catalog) Tip: Journal bearing can only support lateral (radial) force, like By in this problem, while Thrust bearings can support axial and lateral forces, like A, and A, in this case. b) Upon inspection of the shaft, you decide that the cross-section C needs to be evaluated to avoid mechanical failure. Find the resultant internal loadings acting on the cross-section at C. If the shaft diameter at this section is 0.3 mm, what are the average normal and shear stresses at this section? 700 N/m IIII C |--1m+1 m +1 m+15m 2m D 1 kN
