Five toy blocks are glued together to form a beam that supports a shear force of 162 N. Each block has dimensions a = 19 mm and b = 57 mm. Determine the horizontal shear stress in the glue between blocks (1) and (2).

Three toy blocks are stacked to form a channel shape. Each block has dimensions a = 22 mm and b = 66 mm. Determine the vertical distance from the table to the centroid of the shape.

Three toy blocks are glued together to form a beam that supports a vertical shear force of 143 N. Each block has dimensions a = 20 mm and b = 60 mm. Determine the horizontal shear stress in the glue between blocks (1) and (2). The moment of inertia around the horizontal centroidal axis of the beam is 4,280,000 mm4.

A 50-N eagle sits on a tee-shaped post that has a diameter of 59 mm. Determine the magnitude of the largest normal stress in the vertical part of the post. Let a = 0.35 m be the distance from the eagle to the centroid of the post.

Three toy blocks are stacked to form an I-shape. Each block has dimensions a = 10 mm and b = 30 mm. Determine the moment of inertia about the horizontal centroidal axis for the shape.

Three toy blocks are stacked to form an I-shape. Each block has dimensions a = 15 mm and b = 45 mm. Determine the moment of inertia about the horizontal centroidal axis for the shape.

A 52-N eagle sits on a tee-shaped post that has a diameter of 51 mm. Determine the magnitude of the largest normal stress in the vertical part of the post. Let a = 0.40 m be the distance from the eagle to the centroid of the post.
