The check valve is used to regulate pressure in the pipe. (Figure 1) \( \quad \boldsymbol{P a r t ~ A ~} \) The plug at \( A \) is circular. If the stiffness of the spring is \( k=35 \mathrm{kN} / \mathrm{m} \) and its uncompressed length is \( 120 \mathrm{~mm} \), determine the maximum pressure in the tank if the lever is to remain in the horizontal position as shown. Express your answer to three significant figures and include the appropriate units. Consider the beam shown in (Figure 1). Suppose that \( w=400 \mathrm{~N} / \mathrm{m} \). Part A Determine the \( y \) component of reaction at \( A \) using scalar notation. Express your answer to three significant figures and include the appropriate units. X Incorrect; Try Again; 4 attempts remaining Part B Figure 1 of 1 Determine the \( x \) and \( y \) components of reaction at \( B \) using scalar notation. Express your answers in kilonewtons to three significant figures separated by a comma. \( \boldsymbol{X} \) Incorrect; Try Again; 5 attempts remaining The triangular plate, having a \( 90^{\circ} \) angle at \( A \), supports the load Part A \( P=170 \mathrm{lb} \) as shown in (Figure 1). Determine the tension in cables \( B D \) and \( C D \). Express your answers in pounds to three significant figures. Enter your answers separated by a comma. \[ T_{B D}, T_{C D}=[\quad \mathrm{lb} \] Part B Determine the \( x, y, z \) components of reaction at the ball-and-socket joint at \( A \). Express your answers in pounds to three significant figures. Enter your answers separated by commas.
