Two cars (A &B) start simultaneously from point (0) and move in a straight line. One with a velocity of ( 66 m/s ), and an acceleration of (2 m/s ), the other car with a velocity of ( 132 m/s ) and with a retardation of ( 8 m/s ). Find the time which the velocities of the cars are O REDMI NOTE 8 PROance from point (0) where they meet again. AI QUAD CAMERA

Learning Goal: To calculate the maximum allowable stresses in pressure vessels, compute the minimum allowable thickness of pressure vessels to meet certain constraints, and observe and compare properties of different pressure vessel shapes. Engineers are considering two possible vessel shapes for storing fuel. One shape is cylindrical and the other is spherical. Each vessel would be constructed out of the same material such that its hoop stresses and longitudinal stresses would be no greater than 140 MPa. The cylindrical pressure vessel has an inside diameter of dc = 635 mm and a thickness of t = 14 mm . The spherical pressure vessel has an inside diameter of de = 735 mm and a thickness of t = 8 mm. Part A - Maximum allowable pressure in the cylindrical pressure vessel Determine the maximum allowable pressure, pc,max, in the cylindrical pressure vessel. Express your answer in MPa to three significant figures. ► View Available Hint(s) Pc,max = Submit ΑΣΦ Ps,max = Request Answer Submit…

Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?

Learning Goal: To determine the effects of certain geometric shapes, namely fillets and circular cutouts, on the stress distributions inside a rigid body and to determine the maximum applicable axial force in the same rigid body while considering these stress concentrations. The member shown below is made of steel (oallow = 145 MPa ) that is 80 mm thick. The member is subjected to an axial force P that is applied at both ends. Let rf = 10 mm , w = 120 mm , h = 40 mm , and d = 25 mm

3.) A 1000N block is in contact with a plane inclined at 30° to the horizontal. A force P, parallel to and acting up the plane, is applied to the body. If the coefficient of static friction 0.20, a.) find the value of P to just cause motion to impend up the plane and b.) find the value of P to just prevent the motion down the plane.

can u pls show me me how you solve this question in the matlab
