SE DEBE CONTRUIR UNA PARED QUE TENDRÁ 4 METROS DE LARGO POR 3 METROS DE ALTO. SI SE UTILIZARAN LADRILLOS HUECOS Y TENIENDO EN CUENTA QUE ENTRE

LADRILLO Y LADRILLO SE DEBE COLOCAR ALREDEDOR DE DOS CENTÍMETROS DE MEZCLA

PARA UNIRLOS….. ¿ CUÁNTOS LADRILLOS SERÁN NECESARIOS APROXIMADAMENTE PARA

CONTRUIR LA PARED?.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

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
