Question

Review of statics (q4).

please show fbd and work!

(1-14 The coal wagon shown in Fig. P1-14 is used to haul coal from a mine. If the mass of the coal and wagon is 2000 kg, determine the force P required to move the wagon at a con- stant velocity and the forces exerted on the front and rear wheels by the inclined surface. 1 m G 30° 2m 2m 1 m e ts Figure P1-14

Answer 1

solution! 7+-- mg sino since Block will move with content Velocity there fore Net Force Nel fra Net Torque (Ether) ao p = mg sino

Putting values p = 2000 X 9.8X sin3o P = 98009] Anowe - Again N + NB = ng coso - Torque about point EG! (ta) = 0 - C - Ý F (M) X(HA) -(Ne) *(BH) * PX150 MX1 - NB X 2 + 9800X1=0 NB = 9800 + NA 2 Putting values in eq 0 ONA + 9800INA = ang coso INA +9800 = 2x 2000X9.8 x 26130 3N4 +9800 = 33948.195 TMA = (0049.39)M7

Mon = 9800 + 80 49.99 NR = 9800 + 8049.39 NB = 8924. 695 N Answer
