Figure Q1 shows a uniform plank, rests upon a horizontal bench with one end of the bar projecting over the sharp edge of the bench, the bar being at right angles to this edge.  The plank is pulled out of horizontally until the centre of gravity overhangs the edge by a distance a, and is then released.  The plank rotates about the edge and then slides down.

A realistic CAD model of the whole jack must be produced.

A mechanism to spray water onto vehicles at an automated car wash is shown. Classify the four-bar mechanism, based on its possible motion, when the lengths of the links are: a = 12 in b = 1.5 in C = 14 in d = 4 in Complete solution must be included in the file that will be uploaded at the end of assessment. Input the category type of the given four-bar mechanism in the space provided. For example, "DOUBLE CRANK" or "CRANK-ROCKER" etc. (refer to MODULE 1 for the table with the list of different categories.)

BDS. Do this on раper. 1. Draw a FBD for the cylindrical tub before the metal object is added, clearly labeling all forces. 2. Draw a FBD for the cylindrical tub after the metal object is added, clearly labeling all forces. 3. Draw a FBD for the metal object after it is placed in the tub, clearly labeling all forces. 4. Take a clear photo of the FBDS and upload that here. BIU E E E E МacВook Pro %24 & 4 5 6 7 R Y 00 ト

1. How will the date code be applied to the assembly? 2. What paper size is the original version of the print? 3. What is the scale of the original drawing? Thank you, ill be posting more if you are good with engineering please check again soon.

Hello, Can someone help me with this worksheet please?

This is a trebuchet. Draw free body diagram and kinetic diagram for Counterweight box, Sling and Swing arms. draw clearly please. Thank you.

Hello, I have submitted this worksheet for assistance 2x but for some reason it goes white for the answer. Can someone type it out and resend it? Would it be possible to credit those 2 questions back?

Weight and Balance Find the Empty Weight CG location for the following tricycle gear aircraft. Each main wheel weighs 753 pounds, nose wheel weighs 22 pounds, distance between nose wheel and main wheels is 87.5 inches, nose wheel location is +9.875 inches from the datum, with 1 gallon of hydraulic fluid at –21 inches included in the aircraft weight.

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.

Please provide Handwritten answer. show all tge steps and FBD. thank you:)

A significant disadvantage of using a flywheel with a reduced moment of inertia would most likely be: The flywheel would decrease in speed between power strokes of the piston The engine would be more difficult to start The engine as a whole would weight less The flywheel would be subject to higher stresses

A hydraulic press must be used to press-fit two components together in an assembly process. The system must generate at least 975 lb of force to perform the press fit. The piston at the input cylinder is pushed with a force of 250 lb and has an area of 30 in.2. The output can use up to 15 cylinders that are each 30 in.2. How much mechanical advantage is required to gain the necessary force ?

Pls help ASAP

Item 1 used to intermittently operate a piece of equipment at the end of a lifter arm. The lifter is in contact with the highest point of the cam at the instant shown and the lifter is constrained to move only in the vertical direction. The cam has a radius of r = 4.5 in and is rotating about point O, which is offset from the center by a distance c = 3.0 in. The cam's angular position is measured from the positive x axis and is positive clockwise. The angular velocity and acceleration are positive clockwise.

Two gas struts with a extended length of 26", compressed length of 16" and a stroke of 10" with a .39" rod and .866" body is being used to hold a door weighing 40 lbs. prior to use, the owner would like to ensure the ball bearings can hold the load of the gas struts closed. The gas strut is a 20 lb compression gas strut, how much force does it take to keep gas strut closed if you were to push straight down in order to compress. Note: The answer is not 20lbs and I need all equations.

The bearing arrangement depicted below is often used for car wheel hubs because: C The inner bearing always carries more load The bearings carry radial and axial load The opposed bearings can only resist axial loads in a right to left direction The axial loads from cornering are shared equally between the bearings
