The assembly consists of two 10 mm diameter red brass C83400 coper rods AB and CD, a 15 mm diameter 304 stainless steel of EF and a rigid bar G. (Elasticity moduli of brass Eb = 101 GPa, stainless steel Es = 193 GPa) a) If the force P is 3 kN, determine the stretch of rod EF. b) If the stretch of whole assembly (from A to F) is 0.45 mm, determine the force P.

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

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
