Athree-point bending test is performed on a glass specimen having a rectangular cross section of height d=5mm and width b=10mm; the distance between support points is 45mm.
a) compute the flexural strength of the load at fracture is 290n.
b) the point at maximum deflection delta(y) occurs at the center of the specimen and is described delta(y)=fl^3/48ei, where e is the modulus of elasticity and i is the cross-sectional moment of inertia. compute delta(y) at a load of 266n.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
