In your first assignment as Chief Dessert Engineer for the United Cookie Corporation, you design acookie whose interior is a layer of marshmallow surrounded by a ring of chocolate. The top and bottomare round graham crackers, to which the marshmallow and chocolate are attached securely.After the graham crackers are attached, and the entire cookie is in equilibrium at 10°C, there is nostress in the marshmallow or chocolate. The chocolate will separate from the graham cracker if the(vertical) tensile stress in the chocolate exceeds 1.3 × 10³ Pa. What is the maximum temperatureincrease the cookies can withstand without the chocolate separating?chocolate separatingChocolate: Y = 1.5 × 10$ Pa and a =0.0010KMarshmallow: Y = 1.0 × 10ª Pa, a = 0.0025K1%3DAssume the graham cracker does not bend and ignore effects related to expansion in the horizontdirections.15

Determine the instantaneous stress and elongation of a 30 mm diameter bar if a mass of 60 kg falls through a height of 60 mm on to a collar which is rigidly attached to the bottom end of the bar as shown in Figure Q2. The bar is 1.2 m long and is suspended vertically. The Modulus of elasticity, E, for the material of bar is 210 GPa. Take g = 10 m/s2.
Typewritten only ill upvote The uniform horizontal beam supporting the sign is 1.39 m long, has a mass of 12.51 kg, and is hinged to the wall The sign itself is uniform with a mass of 27.08 kg and overall length of 1.35 m. The two wires supporting the sign are each 33.92 cm long, are 34.34 cm apart, and are equally spaced from the middle of the sign. The cable supporting the beam is 3.34 m long. What minimum vertical force must the hinge be able to support without pulling out of the wall? Note: Write your answers with 3 digits after the decimal point.
Please solve it asap !! Strictly don't use Artificial intelligence tools.
A mass of 45 kg falls freely from a height of 2,5 m onto a collar fixed to the bottom end of a vertical steel rod. The rod is 20 mm in diameter and 8 m long. Calculate (a) the instantaneous stress induced in the rod; (b) the instantaneous elongation of the rod; and (c) the strain energy stored in the rod (E = 205 GPa).
What is the area under the stress-strain curve equivalent to? What does the area under the elastic portion of the stress-strain represent?
The assembly shown below consists of a brass shell (1) fully bonded to a ceramic core (2). The brass shell [E = 115 GPa; α = 18.7 x 10-6 /°C] has an outside diameter of 50 mm and an inside diameter of 35 mm. The ceramic core [E = 290 GPa; α = 3.1 x 10-6 /°C] has a diameter of 35 mm. At a temperature of 15°C, the assembly is unstressed. Determine the largest temperature increase that is acceptable for the assembly if the normal stress in the longitudinal direction of the brass shell must not exceed 80 MPa.
help me pls its too hard :(
A metal rod is 50 mm in diameter and 1.3 m long. The rod has a collar on one end and is suspended vertically. The height through which this load may fall if the instantaneous stress is limited to 90 MPa is 1.71870× 10−3 m. The value of Young modulus is 132.40 GPa. 2.1 Calculate an extension when a weight of 30 kN is suddenly lowered onto the collar.2.2 Calculate the force required to cause the maximum stress.
