A 17.0 m-high and 12.0 m-long wall under construction and Its bracing are shown in the figure below. The wall is In stable equilibrium without the bracing but can pivot at its base. Calculate the force (In N) exerted by each of the 10 braces if a strong wind exerts a horizontal force of 715 N on each square meter of the wall. Assume that the net force from the win acts at a helght halfway up the wall and that all braces exert equal forces parallel to their lengths. Neglect the thickness of the wall. (Enter the magnitude.)

A house painter stands 3.00 m above the ground on a 5.00-m-long ladder that leans against the wall at a point 4.70 m above the ground. The painter weighs 663 N and the ladder weighs 108 N. Painter Ladder Driveway Wall 4.70 m 3.00 m Assuming no friction between the house and the upper end of the ladder, find the force of friction that the driveway exerts on the bottom of the ladder. If the force of friction is away from the wall, enter a negative value and if the force of friction is toward the wall, enter a positive value.

Hi I needed help with this question. As shown in the figure below, a uniform beam is supported by a cable at one end and the force of friction at the other end. The cable makes an angle of ? = 30°, the length of the beam is L = 2.00 m, the coefficient of static friction between the wall and the beam is ?s = 0.600 and the weight of the beam is represented by w. Determine the minimum distance x from point A at which an additional weight 2w (twice the weight of the rod) can be hung without causing the rod to slip at point A. X=?

We analyzed the biceps muscle example with the angle between forearm and upper arm set at 90 degree (see figure below). Find the force exerted by the biceps muscle when the angle is 150 degree and the forearm is in a downward position. (Assume that r_1 = 5.0 cm, r_2 = 12 cm, r_3 = 30 cm, m_a = 2.4kg, and m_b = 4.2 kg. Enter the magnitude.) N

for the below figure, the rod of mass 50kg and length 6m is in the equilibrium. It is hinged to a wall at 0. The rod is at an angle of 40˚ above the horizontal and the rope makes an angle of 70˚ with the rod. (a)find the tension in the rope (b)find the force exerted by the hinge 0 on the rod.

The uniform 19.0 kg beam below is 6.4 m long and is perfectly balanced about a point 1.4 m from the left end. What is the mass of the block? (Hint: when calculating the torque due to the weight of the beam, consider all of its mass to be located at its center of mass.)

Q10a The 9.75 m long beam is simply supported at A and B as shown below with a uniformly distributed load (UDL) between A and C of 4.75 kN/m and a concentrated point load of 12.50 kN at point D (i.e., midpoint between C & B). Determine the reaction force RA acting at A in kilonewtons (kN). Assume the beam is weightless and give your answer in kilonewtons (kN) to 2 decimal places. 12.50 kN 4.75 kN/m 1.125 m A 7.50 m 2.25 m C B Answer:
