) The slab shown below is loaded with D = 8 kN/m2 and L= 4 kN/m2
. All beams are 300
mm in width and 600 mm in depth and all columns are square with side length of 300
mm. If the slab is 200 mm thick and is reinforced with 10 mm diameter bars in both
directions, then:
(a)Calculate the design moment of the slab at A.
(b)Calculate the uniformly distributed load on beam B1.​

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
