3. Cast-Iron Weight Using two ropes and a roller chute, two workers unloading a 200 kg cast-iron counterweight from a truck. Knowing that at the instant shown the counterweight is kept from moving and that the positions of points A, B, and C are, respectively, A (0, -0.5 m, 1 m), B (-0.6 m, 0.8 m, 0), and C (0.7 m, 0.9 m, 0), and assuming that no friction exists between the counterweight and the chute, determine the tension in...

To carry a 300-pound cylindrical weight, two workers lift on the ends of short ropes tied to an eyelet on the top center of the cylinder. One rope makes a 20° angle away from the vertical and the other makes a 30° angle as shown in the figure below. Find the vertical component of each worker's force. Round your answer to two decimal places. 300 200 alb a = 300 ||||sin 60° = 116.00 lb;...

3. The fire truck shown in the figure below is parked on an ice covered road. It produces a water jet with a velocity, V 35 which is directed towards the fire as shown. The diameter of the jet is 80 mm and it is positioned on the longitudinal plane of symmetry of the truck. The weight of the truck is 100 kN. The water density, p 996 kg/m3, and the viscosity, 0.00093 kg/ms. Do the following: a) Draw...

A ladder of length 20.0m is carried by a fire truck. The ladder has a weight of 3200N and its center of gravity is at its center. The ladder is pivoted at one end (A) about a pin (Figure 1) you can ignore the friction torque at the pin. The ladder is raised into position by a force applied by a hydraulic piston at C. Point C is a distance 8.0m from A, and the force F rightarrow exerted by...

QUESTION 3 The 1500-kg rear driving truck reaches a speed of 50 km/h from rest in a distance of 60 m up the 10-percent incline with constant acceleration. Calculate the normal force under each pair of wheels and the effective coefficient of friction between the tires and the road during this motion (Hints: the driving force from the friction of the rear wheels, not from front wheels).

Furniture Face Lift refinishes old wood furniture. Their process for refinishing chairs has 8 workers and 4 stations. Each chair starts at the Stripping station, then goes to Priming, then to Painting and finally to Inspection. Where there are multiple workers within a station, each worker works independently on his/her own chair. Assume inventory buffers are allowed between each station.

Example 2 Suppose one truck is parked on a bridge as shown in the Figure. The truck weighs 1000 lb which is acting through its center of gravity (CG). The bridge weighs 200 lbs per feet, which is uniformly distributed. We can assume the bridge is rigid. We want to know what will be the reaction forces at the supports of bridge at the two ends 1000 lbe 200 Ib/ft 25 Force? 50 Force? Figure 1
